Minimax optimization of recursive digital filters using recent minimax results
C. Charalambous · IEEE Transactions on Acoustics Speech and Signal Processing · 1975
The purpose of this paper is to use some recent work by the author on nonlinear minimax optimization to derive an efficient algorithm for the minimax optimization problem. This is followed by the application of the algorithm to the problem of choosing the coefficients of a recursive digital filter to meet arbitrary design specifications on the magnitude or the group delay characteristics.
