Problem 1. Consider the following DT signal 00 x[n] = cos(5πn + m) + [ S[n-mk-3] k= -00 where k is an integer number. Choose a non-zero integer value for m in the given signal and • Determine if the signal is periodic. • If the signal is periodic, find its fundamental period and fundamental frequency. Sketch the even part of x[n]. Show your work. Show your work.
