Michigan State University Department of Electrical and Computer Engineering ECE 366 INTRODUCTION TO SIGNAL PROCESSING Problem Set 9 Spring 2011 Issued: Friday, March 25, 2011 Due: Friday (8:00am), April 1, 2011 1. A signal f ( t ) = sinc(200 π t) is sampled at a rate of (a) 150 Hz, (b) 200 Hz, and (c) 300 Hz. For each of these three cases (i) sketch the spectrum of the sampled signal, (ii) explain if you can recover the signal f ( t ) from the sampled signal, and (iii) if the
