What are the two main uses of a transistor?
a) to act as a switching device; a change in the bias voltage at the base- emitter junction can cause an increase in signal flowing through the transistor through the collector terminal and this cause the output voltage at the collector terminal to change; eg to drop to a low voltage level, this is seen as the transistor device switching on to maximum conduction rate and a low level output at the collector. b) to act an amplifer . whether the input signal is an ac type signal in which case its a signal power amplifer function; eg sound amplifer control circuits , or whether a dc input signal, in which case the input dc signal is amplfied to be reproduced as a bigger signal at the output collector terminal

How does the circuit of a collector modulation work?
The output stage of the transmitter is a high power frequency class C amplifier. Class C amplifiers conduct for only a portion of the positive half cycle of their input signal. The collector current pulses cause the tuned circuit to oscillate or ring at the desired output frequency. The tuned circuit, therefore, reproduces the negative portion of the carrier signal. The modulator is a linear power amplifier that takes the low level modulating signal and amplifies it to a high power level. The modulating output signal is coupled through modulation transformer T1 to the class C amplifier. The secondary winding of the modulation transformer is connected in series with the collector supply voltage Vcc of the class C amplifier.

What is Tri-state logic?
Electronic logic uses just two states, high and low voltage, or "1" and "0". The output of a gate will always be at one value or the other. This is convenient when only a single output is used to drive a signal. In some cases, it is useful to have two or more outputs driving the same signal line. However, if two outputs are linked together, if they have different outputs, there is likely to be damage to the outputs and the level on the line will be un-predictable. A tri-state output has the same high and low levels as standard logic outputs but it has a third state, namely high impedance. A high impedance state means that the output is not transferred to the line so effectively, the output is simply turned off. Another logic gate can now drive the line and the level is entirely predictable. Numerous outputs can now drive a single line as long as only on is turned on at any time.
If both aggregate output and the aggregate price level increase what will happen?
a decrease in need which will in turn surplus the output and decrease the price level. then output will decrease.

What is signal signal conditioning and why do you need it?
In electronics, signal conditioning means manipulating an analogue signal in such a way that it meets the requirements of the next stage for further processing. Most common use is in analog-to-digital converters.In control engineering applications, it is common to have a sensing stage (which consists of a sensor), a signal conditioning stage (where usually amplification of the signal is done) and a processing stage (normally carried out by an ADC and a micro-controller). Operational amplifiers (op-amps) are commonly employed to carry out the amplification of the signal in the signal conditioning stage.So, a signal conditioning circuit includes a logarithmic signal compression circuit for compressing wide dynamic range input signals to a dynamic range which is a predetermined portion of the dynamic range of an output utilization apparatus. There is provided, additionally, means for detecting the presence of the high level signals and superimposing a signal representative of the high level signals on the compressed signals to provide a combined output signal which, while compressed to the range of the output utilization apparatus, contains definable low level and high level signals from a wide dynamic range input signal.
What is the maximum length for BNC cable?
The BNC (Bayonet Neill Concelman) connectoris a very common type of RF connector used for terminating coaxial cable.There is no predetemined maximum length for the coax cable. The maximum length of cable is going to be governed by determining the input signal level, the minimum output signal level, and the signal loss based on the length of the cable between the input and minimum output.
Can you improve voltage level in the range of millivolt into a 15volt?
A voltage amplifier (high input and output impedances) with a gain of 83.5 dB will amplify a signal of 1 millivolt to an output of 15 volts.

What is a transparent latch in a microprocessor?
A transparent latch (or simply a latch) is a digital logic device that can store two stable states with a level sensitive control signal called enable/latch, when this control signal is in the enable state the latch device transparently passes its input signal to its output, when this control signal is in the latch state the latch device holds its output in the current state and ignores the input signal. This behavior is different from flip flops (e.g. D flip flop), which are usually clocked and often edge sensitive not level sensitive.
How can you tell if the head unit output signal is to strong for the amp?
if the head unit can produce sound to your speakers without the amp you have high level output from head unit if your amp only accepts low level input (rca) plugs you must buy a high to low level converter which take speaker high output and reduces it to low ( rca) output and then go to your amp converter is under 20 bucks but most new amp accept hi and low level feed

Can you connect a two-way radio external speaker output to the stereo speakers so that it will override the stereo signal when you get a call?
Yes, absolutely you can. The difficulty is that the controller needed to do the job is not something that can be bought off the shelf. Here is one idea to make the system work: First, take the output from the communications radio and establish the signal characteristics. You may need an attenuator to reduce the voltage of the signal. Once the signal is at the right level, it will need to be connected to an input on the stereo. Additionally, a sensor that will detect an audio signal on the comms radio output or a sensor that detects a valid radio signal on the comms radio is needed. Use the sensor output to trigger a switch from the current input to the comms radio input on the stereo. As an alternative, the same sensor output can be used to switch the speaker signal from the stereo to the comms radio. You will need a separate amplifier to do this as well as a suitable signal switcher to select either of the two speaker signals. The solution is not particularly difficult for an engineer to produce but it is not a straightforward job either.
