Unformatted text preview: EE 362 Assignment 4 • Content : Eigenfunctions, Frequency Response, Suddenly Applied Complex Exponentials • Reading : Course text, pages 40 to 48 of Chapter 2. • Notes : Session 4 Slides. • Assignment Questions : 1. A black box LTI filter has been generated in MATLAB. The filter is implemented as a MAT LAB function, which is in the file a4filter.p (this file is on the website). Given the input x , the output of the filter can be generated using y=a4filter(x); . (a) Determine the type of filter in the black box, either lowpass, bandpass or highpass. (b) Generate a MATLAB script, called a4q1.m, that calculates and displays the magnitude and phase (in degrees) of the filter in a4filter.p at the frequency f = 0 . 3 cycles/sample. To determine the filter response use the eigenfunction e jωn as the filter input. Submit all files needed to execute your mfile (ie. a4filter.p). 2. Which of the following discretetime signals are eigenfunctions of stable, linear, timeinvariant discretetime systems? Show that they are eigenfunctions or they are not.discretetime systems?...
