Abstract :
In this paper, we propose a design of FIR filters with equiripple magnitude and phase responses in complex domain. In every iteration, we use a transformed error response as an ideal frequency response. Since the proposed method does not require any optimization procedure, it can significantly reduce the amount of computation
