Digital filters with lined phase responses that is constant group delay responses are desirable in many uses for signal treating. In this paper, a new method is proposed for scheming maximally smooth IIR filters with constant group delay in the pass band. This paper presents a concept of IIR filters with equalized group delay response. The group delay has been equalized by all pass filter. In this IIR filter design some constant group delay has been introduce and effect of group delay on phase is studied. At some extent of frequency group delay of compensated filter is linear so that phase of the IIR filter is linear at particular range of frequency. This paper looks at a compromise in which the IIR filter is followed by a allpass filter, which adaptively tries to linearize the overall phase response but leaves the magnitude response unchanged.
