Abstract
Through examples, several techniques are explored for controlling intersymbol interference (ISI) in the linear/programming design of the finite impulse response (FIR)-filter portion of a hybrid FIR-filter/analog-filter pulse-shaping system. The most promising technique, the explicit limiting or minimization of peak ISI, obtained as the sum of absolute values of system-pulse samples, results in an unexpected result. A central set of individual system-pulse samples is effectively zeroed, and the rest seem unaffected by the optimization.Keywords
