FIR Filter Designer
===================
This is the second Aminet release of the FilterDesigner.
The program designs optimized Finite Impulse Response
(FIR) Filters. There are optimized versions for the
MC 68000
MC 68020
MC 68040
OS 2.x is required. The program makes use of big
Workbench screens but runs on every standard Amiga.
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.
