Higher modulating frequencies are amplified more than the lower frequencies at the transmitting end of an FM system by a process called
A)full duplex.
B)filtering.
C)pre- emphasis.
D)de- emphasis.

Question

Quizplus · Accepted Answer

Pre-emphasis is a process used in FM systems to increase the amplitude of higher modulating frequencies relative to lower ones at the transmitter, improving the signal-to-noise ratio for higher frequencies.
