5. Transform Analysis of Linear Time-Invariant Systems (eBook)

Overview: In Chapter 5, this companion web site provides exercises to illuminate the ideas of phase, group delay, and poles and zeros.

The Build-a-Figures show how to recreate several figures using filters with dramatic changes in group delay.

The Linear Phase Filter Demo is included in this chapter to show you how a linear phase filter preserves pulse shape, while a non-linear phase filter distorts pulses.

The two MATLAB-based homework problems reinforce analysis skills using MATLAB.

Build-a-Figure

5.5 [baf] Group Delay p282,283 - Three pulses go in. One disappears and another comes out much later.
5.19 [baf] Frequency Response of All-Pass Filters p307 - Use PeZ to see the frequency and phase response of the filters shown in figures 5.19 - 5.21.
5.x [baf] Pulse Distortion Though a Nonlinear Phase Filter p278 - The Linear Phase Demo shows how a pulse is distored as it passes through a nonlinear filter. The goal of this Build-a-Figure is to reproduce the demo.
