Use the stem() function to plot the following discrete-time signals (if complex, plot the amplitude and phase). determine if the signals are power signal or energy signal and find the corresponding power and energy. (when finding the energy of signal with infinite support, use a large enough n to approximate infinity). a) exp(-n) cos(0.2īn) u(n) b) exp(n) u(-n) c) exp(-j0.2min)
