MatchedFilter Design

Area: Electrical Engineering
Matchnfreq is a (free) pulse shaping filter program that finds the polezero locations of a transfer function, H(s), for a matchedfilter design. The transfer function H(s) equals a desired signal (Yout) divided by a given input signal (Yin). Both Yout and Yin are functions of frequency.
The transfer function H(s) has equal sidelobe peak amplitudes in a Bode plot; i.e., Peak i = Peak j for all i, j.
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.
