ECE 301 HW4 Due: 7/5/10 Problem 1 Pg 255, Problem 3.22(b) Problem 2 Pg 255, Problem 3.22(c) Problem 3 Consider two periodic signals, x 1 ( t ) and x 2 ( t ). Signal x 1 ( t ) has period 2 and Fourier Series coefficients a 1 = a - 1 = 2 and all other a k = 0. Signal x 2 ( t ) has period 3 and Fourier Series coefficients a 1 = j , a - 1 = - j and all other a k = 1. Part a: Plot x 1 ( t ) and x 2 ( t ). Part b: Let y ( t ) = x 1 ( t ) + x 2 ( t ). Find the Fourier Series coefficients of y ( t ). Problem 4 Given the Fourier Series coefficients of a continuous-time signal that is periodic with period 4, find the
