EE311: Discrete Systems 1 Homework 3 Chapter 1: Read the end of chapter 14 “solved problems . 1. 15. 8 2. Let h(n)= 4n u(n), find H(z) by using the properties and table of Z-transform. 3. Given the input to a discrete-time LTI system is x(n)=[1,2,1] and the unit-sample response is h(n)=[1,-0.5,1]. The output is denoted as y(n). Obtain X(z), H(z), and Y(z). Unformatted text preview: 4. 15.14 5. For a discrete-time LTI system, let input x(n) =2-n u(n), h(n) = 3 u(n) (a) Obtain the output y(n) through an analytical approach. (b) Obtain X(z) and H(z). (c) Obtain Y(z) using any method. (d) Obtain the pole(s) of Y(z). (e) What types of poles (e.g., simple real-valued pole)? (f) Find y(n) using partial fraction expansion approach....
