What is it called when you convert a digital signal to analog?
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
What is the best signal processing either a analog signal processing?
Digital signal processing is the best compared to analog signal. It is because the digital signal is moreefficienterror freeimmune to noisethan an analog signal
Why the received signal in analog communication is distorted by the channel noise than that of digital communication?
If an RF signal is AM modulated with a analogue signal any noise will add or subtract to the amplitude of the RF signal and will be present in the audio signal after detection, also will the noise add itself to the audio signal, where as in digital communication a slight variation in the amplitude of the signal is of no concern because you only work with ones and zeros, it's high or it's low
Which factor affect data rate of a link?
the bandwidth and the signal to noise ratio
Why same junction box is not used for digital and analog signals?
Signal crosstalk. Most specifically is high speed digital switching noise being picked up by analog circuits and upsetting their operation.
Why digital signals are more noise free than analog signals?
Digital signals are "forced" to be either 1 or 0, whereas analog signals are not. This means that a signal of 0.8 will be pushed to 1 in a digital signal and will remain 0.8 in an analog signal, and 0.2 will be 0 digital and 0.2 analog. This means that in order to overwhelm a digital signal the noise must do much more work to be effective. digital signal have only two states analog have infinite states therefore more susceptible to noise
What is different about the method used to boost digital signal strength compared to the method used to boost analog signal strength?
A digital signal requires a repeater, which retransmits the signal in its original form, and an analog signal requires an amplifier, which increases the strength of both the signal and the noise it has accumulated.
A telephone signal is digitized to reduce noise what type of conversion does this represent?
Analog-to-digital conversion
What converts analog signal information into an analog carrier signal?
Analog Modulation
What converts a message from digital to analog and analog to digital?
An DAC convert digital signal to analog signal i.e Digital to Analog Converter. An ADC convert analog signal to digital signal i.e Analog to Digital Converter.
What is noise in digital photography?
Digital photography noise is a common occurrence in photography when the setting of the ISO is too high or if you are using a cheap digital camera. When you press the shutter on your camera, light hits the sensor, and an analog signal is produced, which is converted to a digital image. If, during this time, something messes up the particles creating the analog signal, then noise is produced. Noise can be reduced in Photoshop www.goldprints.com

What is encoding technique?
There are four possible combinations of encoding techniques -Digital data, digital signal -Digital data, analog signal -Analog data, digital signal -Analog data, analog signal

Does a video use an analog or digital signal?
A video uses the analog signal
Is the input to earphones digital of analog?
The input to the earphones is a a analog signal i.e., electrically generated analog signal.
