Let y = x + n where x and n areindependent zero-mean
gaussian random varibles with differentvariances.
a) plot the correlation coefficientbetween the "observed
signal" y and the "desired signal" x as afunction of the
signal-to-noise ratio
.
b) find the minimum mean squareerror estimator for x in
terms of y. find the mean square error ofthe
estimator.

41/2 - 1 1/3 what is the answer as a fraction?

Tomas is making trail mix using granola and walnuts. he can spend a total of $12 on the ingredients. he buys 3 pounds of granola that costs $2.00 per pound. the walnuts cost $6 per pound. he uses the equation to represent the total cost, where x represents the number of pounds of granola and y represents the number of pounds of walnuts. he solves the equation for y, the number of pounds of walnuts he can buy. answer- b tomas added 6 to both sides of the equation instead of subtracting 6. just took the test

Someone me! if you’re smart you can solve this!
