# Sum of two random variables

jmckennon
Hi,

I've been working on this problem but I feel like I'm over complicating it. If you have a random variable X= a*e(j*phi), where phi is uniform on the interval [0,2pi) and a is some constant, and another random variable Y= b where b is a constant. I'm looking to find the probability density function of the random variable Z=X+Y.

This is probably really simple but from what Ive been trying to do, I can just take the fourier transform of X, fourier transform of Y multiply them, and then take the inverse fourier of that, but it doesn't seem to work. How can I do this?
