An amplifier is used to obtain an amplification of frequency response of a communication signal.
The Amplifier is an electronic circuit that is used to increase the strength of a weak input signal. The process of increasing the strength of a weak signal is known as amplification. An amplifier is used to obtain an amplification of frequency response of a communication signal because reactance of the capacitors in the circuit changes with signal frequency and hence affects the output voltage.
