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.
