Abstract :
In this paper, we proposed the design of quasi-equiripple FIR filters in complex domain. In every iteration, we use a transformed error response as an ideal frequency response. Since the proposed method does not require the Gaussian elimination nor any optimization procedure, it can reduce the amount of computation
