HW 5

Homework 6

Due Wednesday, April 23

Text Problems:

Play with pezdemo, a matlab program, try the following activities: (use pp, zz and add with conjugate options). Sketch the pole-zero plots and the spectrum. Your solution should include a cogent discussion of how pole/zero location affects the frequency response.

	put in complex conjugate poles at (.6364 +/- j*.6364), look at magnitude spectrum, where are peaks and/or valleys (how high/deep are they?)
	complex conjugate zeros at (.7071 +/-j*.7071), look at magnitude spectrum
	Put zeros at (.7071 +/-j.7071), poles at (.6364 +/- j.6364), how does the spectrum change?
	Put zeros at (.6 +/-j.6), poles at (.6364 +/- j.6364), how does the spectrum change?
