FilterDesign Programs
The FilterDesign
package is a pair of programs for designing linear phase
Finite (length) Impulse Response (FIR) filters.
- DFiltFIR
- This program designs minimax approximation FIR filters. It uses the
algorithm developed by McLellan and Parks. It incorporates constraints
on the response as proposed by F. Grenez.
- DFiltInt
- This program designs minimum mean-square error FIR interpolating filters.
The design specification is in terms of a tabulated power spectrum model
for the input signal.
