Title: Improving Passband Characteristics in Chebyshev Sharpened Comb Decimation Filters
Abstract:
First one introduction to the decimation filters is presented. Next, the comb decimation filters are introduced and it is elaborated the necessity for the design of comb compensators. In the following is introduced the sharpening in general and Chebyshev sharpening of comb filters. We present the design of optimal and multiplierless compensators for Chebyshev sharpened comb decimation filters. The narrowband and wideband compensators are elaborated For the narrowband, the compensator with a magnitude response is in a sinusoidal form, while for the wideband, compensator with magnitude responses of two sinusoidal functions is introduced. The optimum design is performed using particle swarm optimization (PSO), while the multiplierless design is realized by presenting optimum parameters in a signed-power-of-two (SPT) form. Unlike the methods in the literature, this approach presents flexibility in design, allowing for an exchange between the quality of optimization and the complexity. Comparisons with the compensators from the literature demonstrated that the proposed method provides much better compensation while requiring fewer or slightly increased number of adders. Possible practical applications and potential future research work are also included.
