Given two stochastic processes, X[n]$X[n]$ and Y[n]$Y[n]$, both being WSS (wide state stationary) and independents. What would be the Average and Autocorrelation function of Z[n] = Y[n] x X[n]$Z[n] = Y[n] X[n]$?
Is the resulting Z[n]$Z[n]$ process also WSS? If so, can the PSD (power spectral density) be calculated?
Thank you.
