Description : State the need of multistage amplifier. Draw frequency response of R-C coupled amplifier.

Last Answer : The need of multistage amplifier The voltage (or power) gain, obtained from a single stage small signal amplifier, is limited. Therefore, it is not sufficient for all practical applications. Therefore, in ... to use a MULTISTAGE AMPLIFIER .  Frequency response of R-C coupled amplifier.
