Pulse shaping filter program that finds the pole-zero locations of a transfer function, H(s), for a matched filter. H(s) equals a -desired- signal (Yout) divided by a given input signal (Yin).

Both Yout and Yin are functions of frequency.

Group delay may also be calculated to compliment a given data set, thus, providing a flat group delay.

Minimizing Intersymbol Interference in a read / write channel for disc drives by shaping and slimming an isolated readback pulse was the main objective for writing this program.

Another improved productivity example do to using Calculus (level) programming.
