PROBLEM 8 Determine whether or not each of the following continuous time signals is periodic. If the signal is periodic, determine its fundamental period. a) x(t) = 3 cos(2t + π/6) b) x(t) = e^{j(πt-2)} c) x(t) = [cos(4πt - π/3)]^2 d) x(t) = {0.2cos(4πt) t >= 0, 0.2cos(-4πt) t < 0} PROBLEM 9 Determine whether or not each of the following discrete time signals is periodic. If the signal is periodic, determine its fundamental period. a) x[n] = 2 cos(5π/7 n + 1) b) x[n] = sin(π/4 n^2) c) x[n] = 2sin(π/4 n) + cos(π/2 n) - 3cos(π/2 n + π/3)
