MASSACHUSETTS INSTITUTE OF TECHNOLOGY DEPARTMENT OF MECHANICAL ENGINEERING 2.161 Signal Processing Continuous and Discrete Fall Term, 2008 Quiz #1 October 16, 2008 Notes: The quiz is closedbook, two sheets of notes are allowed. The time allowed is ninety minutes. There are 4 problems, answer them all. Partial credit will be given. Some possibly useful information is given at the back of this quiz. 1 Problem 1: (20 points) A lowpass filter is to be designed from the power frequency response function 1 2  H ( j )  = 1 + 4 (a) Determine a stable system transfer function based on this specification. (b) Make a polezero plot for the system and determine the filter class (lowpass, etc). (c) What type of design is this (Butterworth, Chebyshev Type I, etc). (d) Transform your filter design to a new filter H 1 ( s ), using the substitution 2 s s 2 + 4 s in H ( s ). (e) How many poles and zeros does H 1 ( s ) have, and what class of filter (lowpass etc) is it?. Problem 2: (20 points) Your advisor (who should remain nameless!) went out and bought you a new lab computer complete with A/D converters that will sample up to 10,000 samples/second. Without consulting you he also went and bought...
