These programs are for the design of symmetric equiripple FIR filters achieving specified Chebyshev errors in each band.

Download all programs above as a tar file named allprogs.tar. Unpack the tar file with the UNIX command `tar' (e.g., `tar -xvf allprogs.tar').

Download the programs individually.
