Q1: Consider the following signals x1[n] = 8[n 1] + 8[n+ 1] + sin xz[n] = U[n 1] + U[-n 1] + 8[n] + e -24m +j sin m(Gm) ***n). a) Determine if the signals are periodic or not. If yes, find the fundamental period N, of each one. You need to justify your answer to get the mark. b) Determine if the signals are even, odd, or neither even nor odd. You need to justify your answer to get the mark. c) Find the even and odd components of each signal
