Let y= x+n where x and n are independabt zero -mean
gaussianrandom variable with different variance
a. plot the correlation coeffiecient between the"observed
signal " y and the "desired signal" x as a function ofthe signal to
noise ratio ox/os.
b. find the minimun mean sqaure error estimator for x in
termof y. find the mean square error for the estimator.

i use my brain for prombles like this maybe you could try it

step-by-step explanation:

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
