The output of a balanced modulator in an SSB transmitter being modulated with a voice intelligence signal is:
A) sinewave at the carrier frequency
B) SSB
C) DSB-SC
D) conventional AM

Question

Quizplus · Accepted Answer

A balanced modulator in an SSB (Single Side Band) transmitter, when modulated with a voice intelligence signal, outputs a Double Sideband Suppressed Carrier (DSB-SC) signal. This is because it suppresses the carrier frequency, leaving only the upper and lower sidebands, which is a step in generating an SSB signal.
