1.	Which one of the following is not a useful quantity for comparing the noise performance of receivers?(a) Input noise voltage(b) Signal To Noise Ration(c) Noise Figure(d) Figure of meritI had been asked this question in exam.This key question is from Noise for DSB-SC in division Noise of Analog Communications
Answer» The correct OPTION is (a) INPUT noise voltage The best explanation: Noise performance of different RECEIVERS cannot be compared on the BASIS of input noise voltage. It can be calculated on the basis of figure of merit, or noise figure, or on the basis of equivalent noise resistance.
