Abstract :
A simple extension to the window design method is proposed that provides the flexibility to specify independently the passband ripple and stopband ripple. The modification to the routine is based on creating an additive component which, when applied to the filter, can redistribute the concentration of z-plane zeros in the passband and stopband regions of the z-plane. Some examples and comparisons are also presented
