Abstract :
A simple program is proposed for the computation of group delay characteristics of anti-aliasing filters. These anti-aliasing filters are designed as a combination of elliptic amplitude filters and all-pass delay equalizers. The group delay of the elliptic filters is equalized using an interpolation procedure and a least-mean-square routine. Results for several anti-aliasing filters, which are solved using this computer program, are included. The experimental results for LC and RC anti-aliasing filters confirm all the theoretical considerations
