ECE 130A: Signal Analysis and Processing Prof. Michael Liebling Fall 2009 TAs: Jingning Han, Hari Sivakumar Distribution: Monday, 1 November 2010 Homework Due: Tuesday, 9 November 2010 at 6:00 p.m. University of California, Santa Barbara Homework 5 Problem 1: Fourier Transform Computation (15 Points) Compute the Fourier transform of each of the following signals: (a) x ( t ) = ( 1 - t 2 , 0 < t < 1 0, otherwise. (b) x ( t ) = e -| t | cos(2 t ) (c) x ( t ) = sin(2 π t ) 2 π t sin[ π ( t - 1)] π ( t - 1) Problem 2: Inverse Fourier Transform Computation (15 Points) Compute the inverse Fourier trans- form of each of the following signals: (a) X (j ω ) =- πδ ( ω ) + πδ ( ω - 2 π ) + πδ ( ω + 2 π ) (b) X (j ω ) = 1, 0 ω 1 - 2, - 2 ω < 0 0, otherwise. (c) X (j ω ) = [ u ( ω + 1) - u ( ω - 1)]e j( - ω /2 + π ) Problem 3: System Frequency Response (25 Points) An LTI system has impulse response h ( t ) = u
