In this paper, a new Chebyshev approximation (amplitude and phase simultaneous approximation) method for IIR digital filters is proposed. The proposed algorithm is based on the Remez algorithm. By solving the eigenvalue problem at each iteration, the frequency characteristic of the filter is interpo
