Unformatted text preview: ECE220 Signals and Information Spring 2008 Homework 3: Due Monday, Feb 18, at 10:08am Drop your homework in the collection box marked ECE220 Spring 2008, homework , located on the second floor of Phillips at the south entrance to 219 Phillips. Print your name, NetId, and lab section in the top right corner on all pages. NOTE: This homework is based on lectures 7-10 and Chapters 5, 6 and 7 in the textbook. Problem 1 The textbook uses [ n ] to denote the discrete impulse signal. The delayed by n versions of the impulse is then the signal [ n- n ]. Write the finite duration signal x = [0 , 1 , , ,- 1] in terms of [ n ] and its delayed versions. Write the signal y [ n ] = [ n- 3] * x [ n ] * [ n- 2] in terms of [ n ] and its delayed versions. Problem 2 Consider a (causal) LTI FIR filter with the impulse response h [ n ] = [ n- 1]- 2 [ n- 2]- [ n- 3]. (a) Write the difference equation (see equation 5.1 in the textbook for the definition of a dif- ference equation) for the FIR filter.ference equation) for the FIR filter....
