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.
