Effect on the deviation d of an FM signal when it is passed through a mixer
What is the effect on the deviation d of an FM signal when it is passed through a mixer?
C) Becomes half
d) Remains unchanged
Correct Answer :Remains unchanged
When a carrier is Frequency modulated, the output signal has the frequency deviated above and below the carrier frequency, this is known as Deviation.When the FM signal is passed through a mixer, the mixer changes the carrier frequency but the deviation remains unchanged.
