| Abstract(in English) | In this paper, we present a new numerical method for the Chebyshev approximation of minimum phase FIR digital filters. This method is based on solving a least squares (LS) problem iteratively. At each iteration, the desired response is transformed so as to have an equiripple magnitude error. This method makes it possible to design minimum phase FIR filters whose magnitude error is equiripple. Using this method, an equiripple solution is obtained very quickly with less computational complexity. Since the proposed methods do not require any time-consuming optimization procedure, they require less computational complexity than conventional methods. Finally, we show some examples to illustrate the advantage of our proposed methods. |
