consider a communication channel corrupted by noise. let X bethe value of the transmitted signal and Y be the value of thereceived signal. assume that the conditional density of Y given(X=x) is Guassian, that is, fy/x(y/x)=1/√2πσ*σexp(-(y-x)squared/2σsquared).
and x is uniformly distributed on[-1,1].what is the conditional probability density of X given Y (i.e fx/y(x/y)?)
