Short: FIR Filter Designer V1.1 Author: harald.zottmann@ntc.nokia.com Uploader: harald.zottmann@ntc.nokia.com Version: 1.1 Type: misc/sci Replaces: misc/sci/FIRDesign* FIR Filter Designer =================== This is the third Aminet release of the FilterDesigner. The program designs optimized Finite Impulse Response (FIR) Filters. 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.
