- FIR Filter Designer
- ===================
-
- This is the fourth Aminet release of the FIR FilterDesigner.
- The program designs optimized Finite Impulse Response Filters.
-
- Amiga OS 2.x is required. The program requires a minimum Workbench
- screen size of 640x400.
-
- The FIR Filters designed by the program FIR Filter Designer
- can be loaded by the program AudioLab16 from Maurizio Ciccione.
- AudioLab16 can be found on the Aminet in the directory /mus/edit.
-
- The problem of designing finite impulse response (FIR) digital
- filters experienced great activity in the early 1970`s. Most of
- this work was directed at the problem of optimal filter design,
- in the weighted Chebyshev sense. The algorithm for this program,
- by McClellan, Parks and Rabiner, will design the optimal Chebyshev
- approximation for linear phase filters. The Chebyshev optimization
- is done very efficiently by means of the Remez exchange algorithm,
- and this particular FIR filter design program has found wide use.
