1.	Why frequency fogging is used in a carrier system?(a) to reduce noise(b) to reduce cross talk(c) to converge frequencies(d) to reduce distortionThe question was posed to me during an interview.I want to ask this question from Comparison Between FM and PM topic in division Noise of Analog Communications
Answer» CORRECT choice is (b) to REDUCE cross talk Easy explanation: The interchanging of the frequencies of carrier channels to accomplish specific purposes. It is USED to prevent feedback and oscillation. It is also used to reduce cross-talk and also to correct for a HIGH FREQUENCY response slope in the transmission line.
