Question
Please answer true and false and try to give your reasoning. Reasoning is not important, but its a plus. Ill give you a high rating
6) fy your answers: of the following statements (a which are FALSE. You do not are TRUE and (b gle (b) Amplitude on is a non-linear modulation technique. (FM) e modulation is not (c) We need not very sensitive to noise compared to frequency modulation sens (a) Consider two rd, ep ator in a phase-lock loop to demodulation an FM signal. df the p ) and fy() o rando is e the he pdfs of (() where e denotes the convolution operator, fx() and Jy s of RVs X and Y, respectively two random variables (f) If a random uncorr es are uncorrelated, they are independent. ocess is strict sense stationary (SSS), its mean must be a constant ProblemExplanation / Answer
a)TRUE..Because in angle modulation information is stored in the phase of carrier signal.
b)FALSE...Because in amplitude modulation information is stored in amplitude of carrier signal and most of noise is amplitude based.
c)TRUE
d)TRUE..pdf of rv which is sum of two rv's is convolution of those rv's pdfs.
e)TRUE...random variables are said to be uncorrelated if their covarince is zero...E(XY)-E(X)E(Y)=0..This is possible only when they are independent.
f)TRUE
