FIR and IIR Filter Design AlgorithmsSeveral Matlab programs are available for the design of digital filters by several different approaches.
After down loading the software, move the program file to a new, empty directory. Then uncompress the file using the unix command 'uncompress' (e.g., 'uncompress butter.tar.Z') and unpack the archive using the UNIX command 'tar' (e.g., 'tar xvf butter.tar').
The following sections describe some of the filters that can be obtained with the available Matlab programs.
- Allpass Filter Design
- Constrained Least Square FIR Filter Design
- Generalized Digital Butterworth Filter Design (FIR and IIR)
- Exchange Algorithms Complementing the Parks-McClellan Algorithm
- Two Channel Orthogonal Filter Banks (Wavelet System)
- Symmetric FIR Filters - Flat Passbands, Chebyshev Stopbands
