These programs are for the design of symmetric FIR filters achieving specified Chebyshev errors in the stopband and a specified degree of flatness in the passband.

Download all programs above as a tar file named fircheb.tar. Unpack the tar file with the UNIX command `tar' (e.g., `tar xvf fircheb.tar'). Doing so will create a directory called `fircheb' containing the programs listed above.

Download the programs individually.
