Interactive DSP Demonstrations
This page provides links to interactive demonstrations of DSP concepts.
- Interactive Digital Filter Design - Lets you design simple
IIR and FIR filters interactively. Includes source code in C and C++.
- CMSA
Filter Designer - Designs a digital filter and draws its frequency
response.
- Polyphase Two-Path Filter Designer - Calculates
floating-point coefficients of the two-path polyphase structure first described
by F. Harris, et. al. (Requires Java.)
- Poles and Zeroes - Lets you move around poles and zeroes, and
see the magnitude and phase of the frequency response change. Includes Java
source code.
