Let e[n] denote a white-noise sequence, and let s[n] denote a sequence that is uncorrelated with e[n].

Question:

Let e[n] denote a white-noise sequence, and let s[n] denote a sequence that is uncorrelated with e[n]. Show that the sequence

y[n] = s[n]e[n]

is white, i.e., that

E{y[n] y[n + m]} = Aδ[m],

where A is a constant.
