---

These programs produce symmetric lowpass, highpass, and multiband FIR filters for which the square error between the realized and desired frequency response amplitudes is minimized subject to a constraint on the maximum size of the pass and stopband ripple sizes.

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.
