  • Abstract
    The letter deals with the special case of general-parameter filters that yield Cheby¿shev characteristics. The solution gives a family of Cheby¿shev responses with monotonic stopband and equiripple passband characteristics. These characteristics belong to combinations of the sin (¿T/2) and tan (¿T/2) formulations and it is shown that under the condition of maximum sharpness at cutoff the tan (¿T/2) formulation is unique.
