You will have signal degradation unless you use the amplifier.
Amplifiers are the device which are used to amplify a signal Multistage amplifier are use to amplify a signal into a desire level
I think Amplifier is use for direct signal or D.C signal & the main function of amplifier is to make that signal sharp(powerful) so that a microprocesser process it.
To trace a problem in an amplifier. Send in a signal and trace its' path.
obtaining voltage gain of a weak signal
Reduce the distortion in output signal.
Increase the incoming signal between every even distance
Increase the incoming signal between every even distance
A biderectional cable amplifier with a bypass is excellent for use with digital TV, because it amplifies the return signal. Using a unidirectional cable amplifier can result in some channels that do not work because the return signal is not amplified.
power amplifiers are the amplifier which raise the power levels of the signal.the power amplifier may also defined as a device which converts dc power to ac power and whose action is controlled by the ac input signal. Power amplifiers are also known as "LARGE SIGNAL AMPLIFIER".the term large signal arises because they use large part of load line for their operation,but the small signal amplifiers are use only 10% load line for their operation.
One of the several uses of an RC coupled amplifier is to amplify the given input signal. It makes use of a sinusoidal input signal.
to amplify a small signal to sufficient level,so that it can travel to a large distance from first stage till the last stage
Usually to amplify the video signal across long distances of cable. This is necessary to maintain quality and consistency of the video signal in runs of 100 ft. or more. The word "video" means wideband. A video amplifier is used for any wideband signal.
