Unformatted text preview: x ( n ). Then evaluate y ( n ) when the x ( n ) = u ( n ) or x ( n ) = r ( n ). In part h, the phase response is given by n H ( ω ) = tan − 1 p Im ( H ( ω )) Re ( H ( ω )) P In part i, since H ( ω ) is conjugate symmetric, you can use the expression at the bottom of page 297 to calculate y ( n ). 3. Problem 7 in chapter 9 4. Problem 10 in chapter 9 5. Find the the frequency response of a continuoustime system that has the impulse response below. Hint: Remember that if h ′ ( t ) = h ( tτ ) then the frequency response of h ′ ( t ) is e − iωτ times the frequency response of h ( t ). Shift the signal around to make the integration easier and then multiply the result by a complex exponential. A 2T T t 1...
