[ = E[s[n]s[n+k]] + E[s[n]w[n+k]] + E[w[n]s[n+k]] + E[w[n]w[n+k]] ] Example Solution Entry Problem 3

: Always define new symbols the first time they appear. 4. Example Solution Entry Problem 3.7 (from “Random Processes” chapter): Let ( x[n] = s[n] + w[n] ), where ( s[n] ) is a zero‑mean WSS signal with autocorrelation ( r_ss[k] ), and ( w[n] ) is white noise with variance ( \sigma_w^2 ), uncorrelated with ( s ). Find the autocorrelation ( r_xx[k] ) and power spectral density ( S_xx(e^j\omega) ). Solution: Example Solution Entry Problem 3
