1.	In frequency modulation, there is a large increase in noise and hence decrease in the signal to noise ratio.(a) True(b) FalseThis question was posed to me in semester exam.This interesting question is from Hilbert Transform topic in section Double Sideband Suppressed Carrier Modulation of Analog Communications
Answer» The correct answer is (b) False The BEST I can EXPLAIN: In communication system, Signal-To-NOISE ratio (SNR) is a measure of the amount of signal PRESENT compared to the surrounding noise. It is the ratio of signal power to noise power. Thus in frequency modulation, there is a large decrease in noise and hence increase in the signal to noise ratio.
