Appendix 8A Example Source Code
The companion Web site includes eight different filter models, which are listed in Table 8A.1. The first seven models listed are used for modeling “classical” analog filters—Butterworth, Bessel, Chebyshev, and elliptical. The final model listed simulates an arbitrary filtering device based on the swept amplitude and phase responses of the subject device.
8A.1 Classical Filters
PracSim supports two different approaches for simulating analog filters. One approach uses numerical integration, as discussed in Section 8.4, and the other approach uses IIR sampled-data filters, ...
