A unified quadratic semi-infinite programming approach to time and frequency domain constrained digital filter design
Yan Liu, Chien Hsun Tseng, Kok Lay Teo · Communications in Information and Systems · 2002
A unified quadratic semi-infinite programming approach is introduced to solve digital filter design problems with time or frequency-domain specification.An algorithm based on this approach is developed and the corresponding convergence result is presented.This computational method is then applied to the optimum filter design problems subject to time and frequency domain specifications, namely the time domain envelope constrained filter design problems and the frequencydomain least square FIR filter design problems.For illustration, two examples are given.
