Consider the periodic signal x(t) given by the expression x(t) = (2+2j)e-13t - 3je-12t +5+3je/2t + (2-2j)e/t a) What is the fundamental frequency of x (t)? b) Find and plot the magnitude and phase of the Fourier series coefficients as a function of frequency. c) Is x (t) a real signal? Why? d) Compute the total power of x(t) using Parseval's relation.
