Dear all: This question includes Up-sampler and WSS concept..may I have any
idea from you? Thanx :-)
Question:
Let x[n] be a WSS process with auto-correlation function R[m].
Then x[n] goes into a up-sampler with coefficient L to get an
output y[n]. Finally, y[n] goes into a FIR filter to get an
output z[n]. Determine whether the random process z[n] also WSS?
