Abstract

In the present paper a hypothetical technique for constant group delay and shortening of transients in response of phase compensated time varying chebyshev filters have been discussed. The concept is utilizing the phase compensated time varying chebyshev filter by adding all pass section to it and the effect of all pass sections on group delay and reduction of transient present in noisy rectangular signal have been studied. The paper contains the simulation results of the proposed filter and results confirming the effect of all pass sections on group delay and reduction of transient present in noisy rectangular signal.
