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. For more info, see Kost, R. and P. Brubaker;
