Match n Freq 5.10 descriptions Pulse shaping filter program that finds the pole-zero locations of a transfer function H for a matched filter. H equals a -desired- signal divided by a given input signal . Both Yout & 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 & slimming an isolated readback pulse was the main objective for writing this program.
