Question

Base modulation is preferred over collector modulation of a class C transistor because it has high power output per transistor.

(a) True

(b) False

This question was addressed to me in a national level competition.

My query is from Demodulation of SSB with Large Carrier topic in portion SSB Modulation of Analog Communications

Answer 1

Correct answer is (b) False

For explanation: Base modulation is preferred over collector modulation of a class C transistor because low modulating power is required and collector saturation prevents complete modulation of a signal. Generally, Collector modulation has more advantages over Base modulation like high linearity, better collector efficiency and such like.
