Transistor Amplifier

Question
21 out of 24
 

Why is gain of RC coupled amplifier constant in mid-frequency range?

 

In mid-frequency range, the reactance of coupling capacitor decreases and the gain increases. On the other hand, due to low capacitive reactance, there will be higher loading effect and gain will be reduced. As the two different effects neutralise each other, gain of RC coupled amplifier is constant in mid-frequency range.
