This paper applies a novel artificial bee colony algorithm to solve the design problem of allpass digital filters. We wish that the phase response of allpass filter can meet the desired specification. To achieve this aim, the ABC algorithm is utilized to update the related filter coefficients such that certain cost function of the algorithm can be minimized as possible as much. Finally, numerical simulation results will demonstrate the feasibility and effectiveness of the proposed scheme.
