Interactive minimax design of linear-phase nonrecursive digital filters subject to upper and lower function constraints

This is the authors' abstract. We don't add key points for this paper.

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
