Question B-003-012-006

What is one advantage of carrier suppression in a double-sideband phone transmission?

Correct Answer

More power can be put into the sidebands for a given power amplifier capacity

Explanation

The carrier contains no information but consumes significant power (in standard AM). Suppressing it allows the transmitter's power to be concentrated in the information-carrying sidebands (as in SSB or DSB-SC).
