Consider a full-wave rectifier that has as output a periodic signal x(t) of fundamental period T₀= 1 and a period of it is given as

(a) Obtain the Fourier coefficients X_k.

(b) Suppose we pass x(t) through an ideal filter of transfer function H(s), determine the values of this filter at harmonic frequencies 2Ï€ k,= 0, ±1, ±2, ..., so that its output is a constant, i.e., we have a dc source. Use MATLAB to plot the magnitude line spectrum of x(t).
