The set top box that your provider gives you is what converts the Digital signal to the analog signal.

The digital signal is compressed at the provider and sent to the end user. The "tuner" (which can be built into a tv, a set top box or a cable card) Then decompresses the digital signal and converts it into an analog signal.

There is much more to this did not know how technical you wanted your answer.

What is the difference between analog and digital electronics?

An anlogous signal represents a slowly varying quantity with respect to time . A sinusoidal souce is an example of an anlogue signal. The digital signal is one which has only two stable staes.Either On or OFF. During On full signal and during Off No signal. We can also think of Digital signal as the output of an amplifier with input over driven with an analogue signal. its ouput saturates and gives full DC ouput voltage when it is ON and gives zero ouput for OFF. Uma1976 An analog signal is a variable signal, where as a digital signal is simply on or off. for example a video game steering wheel. With analog you can turn slightly anywhere between 0-90 degrees. With digital you can ONLY turn 90 degree's or 0 degrees'. This also works with buttons. Analog buttons can calculate how hard they are being pressed. Digital buttons only register if they are on, or off. ---- Analog electronics receive, process or output analog signals. Digital electronics receive, process or output digital signals. An analog signal is infinitely variable (usually between some limits). Its value could be 3, 3.2, 3.25, 3.257, 3.2573, etc. The signal "flows" from one value to another passing through the infinite number of values in between. For example a sine wave. A digital signal has discreet values. There are usually a finite number of possible values. The signal has steps instead of a smooth flow. For example, it might have a value of 3 or 4, but there is no such thing as a value of 3.5. Using a step analogy, you can stand on the 3rd step of a stair case, or the 4th step, but you can't stand on the 3.5th stair - it just doesn't exist. Note that either type of signal can be made to approximate the other, usually to any level of accuracy that is necessary. Also note, because many digital signals are binary (either on or off, 1 or 0), the terms digital and binary are sometimes confused. A digital signal can have more than two states, so not all digital signals are binary. But, all binary signals are digital. That is, binary signals are a subset of digital signals. ANALOG is not ONLY sinusoidal but it can be DC direct current. Consequently a limitless variably information. Is it better then digital NO WAY at very small quantity the noise is ambiguous as signal while digital has only 2 states true or false.


What the conversion from analog to digital mean?

Analog phone lines. Analog signals. Digital security. Digital PBX. Analog-to-digital adapters. What does it all mean? In the telecom world, understanding analog versus digital isn't as simple as comparing one technology to another. It depends on what product-and in some cases, which product feature-you happen to be talking about. Analog at a glanceAs a technology, analog is the process of taking an audio or video signal (in most cases, the human voice) and translating it into electronic pulses. Digital on the other hand is breaking the signal into a binary format where the audio or video data is represented by a series of "1"s and "0"s. Simple enough when it's the device-analog or digital phone, fax, modem, or likewise-that does all the converting for you. Is one technology better than the other? Analog technology has been around for decades. It's not that complicated a concept and it's fairly inexpensive to use. That's why we can buy a $20 telephone or watch a few TV stations with the use of a well-placed antenna. The trouble is, analog signals have size limitations as to how much data they can carry. So with our $20 phones and inexpensive TVs, we only get so much. Enter digitalThe newer of the two, digital technology breaks your voice (or television) signal into binary code-a series of 1s and 0s-transfers it to the other end where another device (phone, modem or TV) takes all the numbers and reassembles them into the original signal. The beauty of digital is that it knows what it should be when it reaches the end of the transmission. That way, it can correct any errors that may have occurred in the data transfer. What does all that mean to you? Clarity. In most cases, you'll get distortion-free conversations and clearer TV pictures. You'll get more, too. The nature of digital technology allows it to cram lots of those 1s and 0s together into the same space an analog signal uses. Like your button-rich phone at work or your 200-plus digital cable service, that means more features can be crammed into the digital signal. Compare your simple home phone with the one you may have at the office. At home you have mute, redial, and maybe a few speed-dial buttons. Your phone at work is loaded with function keys, call transfer buttons, and even voice mail. Now, before audiophiles start yelling at me through their PC screens, yes, analog can deliver better sound quality than digital…for now. Digital offers better clarity, but analog gives you richer quality. But like any new technology, digital has a few shortcomings. Since devices are constantly translating, coding, and reassembling your voice, you won't get the same rich sound quality as you do with analog. And for now, digital is still relatively expensive. But slowly, digital-like the VCR or the CD-is coming down in cost and coming out in everything from cell phones to satellite dishes. When you're shopping in the telecom world, you often see products touted as "all digital." Or warnings such as "analog lines only." What does it mean? The basic analog and digital technologies vary a bit in definition depending on how they're implemented. Read on. Phone linesAnalog lines, also referred to as POTS (Plain Old Telephone Service), support standard phones, fax machines, and modems. These are the lines typically found in your home or small office. Digital lines are found in large, corporate phone systems. How do you tell if the phone line is analog or digital? Look at the back of the telephone connected to it. If you see "complies with part 68, FCC Rules" and a Ringer Equivalence Number (REN), then the phone and the line are analog. Also, look at the phone's dialpad. Are there multiple function keys? Do you need to dial "9" for an outside line? These are indicators that the phone and the line are digital. A word of caution. Though digital lines carry lower voltages than analog lines, they still pose a threat to your analog equipment. If you're thinking of connecting your phone, modem, or fax machine to your office's digital phone system, DON'T! At the very least, your equipment may not function properly. In the worst case, you could zap your communications tools into oblivion. How? Let's say you connect your home analog phone to your office's digital line. When you lift the receiver, the phone tries to draw an electrical current to operate. Typically this is regulated by the phone company's central office. Since the typical proprietary digital phone system has no facilities to regulate the current being drawn through it, your analog phone can draw too much current-so much that it either fries itself or in rare cases, damages the phone system's line card. What to do? There are digital-to-analog adapters that not only let you use analog equipment in a digital environment, but also safeguard against frying the internal circuitry of your phone, fax, modem, or laptop. Some adapters manufactured by Konexx come designed to work with one specific piece of office equipment: phone, modem, laptop, or teleconferencer. Simply connect the adapter in between your digital line and your analog device. That's it. Or you can try a universal digital-to-analog adapter such as Hello Direct's LineStein®. It works with any analog communications device. Plus, it's battery powered so you're not running extra cords all over your office. Cordless phonesThe very nature of digital technology-breaking a signal into binary code and recreating it on the receiving end-gives you clear, distortion-free cordless calls. Cordless phones with digital technology are also able to encrypt all those 1s and 0s during transmission so your conversation is safe from eavesdroppers. Plus, more power can be applied to digital signals and thus, you'll enjoy longer range on your cordless phone conversations. The advantage to analog cordless products? Well, they're a bit cheaper. And the sound quality is richer. So unless you need digital security, why not save a few bucks and go with an analog phone? After all, in home or small office environments where you may be the only cordless user, you won't have any interference issues. Keep in mind, when talking about digital and analog cordless phones, you're talking about the signals being transferred between the handset and its base. The phones themselves are still analog devices that can only be used on analog lines. Also, the range of your cordless phone-analog or digital-will always depend on the environment. Cellular phonesPerhaps the most effective use of the digital versus analog technology is in the booming cellular market. With new phone activations increasing exponentially, the limits of analog are quickly being realized. Digital cellular lets significantly more people use their phones within a single coverage area. More data can be sent and received simultaneously by each phone user. Plus, transmissions are more resistant to static and signal fading. And with the all-in-one phones out now-phone, pager, voice mail, internet access-digital phones offer more features than their analog predecessors. Analog's sound quality is still superior-as some users with dual-transmission phones will manually switch to analog for better sound when they're not concerned with a crowded coverage area-but digital is quickly becoming the norm in the cellular market. What to buy?The first thing to consider when buying analog or digital equipment is where you'll be using it. If you're buying for a proprietary PBX phone system, you'll need to get the digital phone designed for that particular system. Need to connect a conferencer on your digital system? Opt for a digital-to-analog adapter. Shopping for home office equipment? Most everything you'll consider is analog. Want an all-in-one cellular phone-paging, voice mail, web? A digital cellular phone will deliver it all. In fact, the only head-scratcher may be your cordless phone purchase. Looking for security and distortion-free conversations in your small office? Go with a digital 900 MHz or 2.4 GHz cordless phone. Using a cordless at home? An analog phone will give you the richest sound quality and usually enough range.

What is the difference between digital multitester and digital multimeter?

An analog multimeter measures values directly and is displayed using a meter. calibratin is done manually by adjusting the meter needle. A digital multimeter collects data at discrete times and the display is usually through LEDS. There is a bandwidh limit and calibration is often done with a click of a button which is much simpler compared to manually tuning the needle on an analog device


What is the difference between analogue and digital system?

the main difference in analoge and digital system is analog is continues type of data and ditital is discreate type of data. e.g old galvanometer having needle is analog but new multimeter is digital in which voltage and current is shown in digits... analog is not much accurate..but digital is accurate...

What is the term for a device that converts digital data from a computer into analog signals and back again?

The devices are known very simply as analog to digital converters and digital to analog converters. They are frequently shorted to A-D and D-A converters. A complete analog to digital converter will not only convert the analog signal into a set of numbers, it will also format the digital data ready to deliver to the next step in the signal chain. In television, this means generating a fairly complex stream of data that will carry not only the picture but audio and other data as well. Digital to analog converters reverse the process and use the incoming data to generate an analog signal. In television, well know examples are the digital set top boxes. They receive digital data from an antenna and convert the numbers into analog audio and video signals.

What is the transfer of digital or analog data using digital or analog signals?

The transfer of digital or analog data using digital or analog signals refers to the process of transmitting information from one device to another, either through digital signals or analog signals. Digital signals are electronic signals that represent binary data, while analog signals are continuous signals that represent continuous data. The method of transfer depends on the type of data being transmitted and the technology being used for the transfer. For example, digital data can be transferred using digital signals through a computer network, while analog data can be transferred using analog signals through a telephone line. Regardless of the method used, the goal of the transfer is to accurately transmit the information from one location to another.


Which device is used to convert analog signals to digital signals?
