Homework Due: Tuesday, 16 November 2010 at 6:00 p.m. University of California, Santa Barbara Homework 6 Problem 1: Fourier Transforms (20 Points) (a) Compute the frequency response H (j ) of the impulse response h ( t ) (and sketch its magnitude) using the Fourier transform relationship X (j ) = Z - x ( t )e- j t d t , when h ( t ) is given by h ( t ) = e- 2( t- 1) u ( t- 1). (b) Compute the response y ( t ) to the input signal x ( t ) = sin(2 t- /2). Problem 2: Fourier Transform Computation (25 Points) Determine and sketch the magnitude | X (j2 f ) | of the Fourier transform for the following signals. State for each waveform whether it is a baseband or bandpass signal (the definitions are to be applied loosely, with most of the frequency content being in a band around DC for a baseband signal, and most of the...
