What is the purpose of a balanced modulator?
A)To produce an output frequency that varies in response to changes in a control voltage.
B)To change frequency in response to a DC control voltage applied to it.
C)To allow a range of frequencies to be generated from a stable, single-frequency reference.
D)To suppress the carrier, leaving only the two sidebands.

Question

Quizplus · Accepted Answer

The purpose of a balanced modulator is to suppress the carrier, leaving only the two sidebands. This is achieved by combining the original signal with a carrier wave that is 180 degrees out of phase, resulting in cancellation of the carrier wave in the output signal.
