Interactive minimax design of linear-phase nonrecursive digital filters subject to upper and lower function constraints
H. S. Hersey, D.W. Tufts, James T. Lewis · IEEE Transactions on Audio and Electroacoustics · 1972
The general Remes exchange algorithm and its implementation are discussed briefly An analog of the exchange algorithm is applied to the problem in which upper and lower constraints are imposed on the frequency response of a nonrecursive digital filter with linear phase. A typical design example is presented with rather tight constraints in the passband
