Abstract In this paper, we introduce new weighted FIR median hybrid (FMH) filters consisting of combinations of averaging and ramp predicting FIR substructures, the input signal and the weighted median operation. We analyze two weighted FMH filter structures in detail. Due to the selection of subfilters the center weighted FMH (CWFMH) filter structure has low-pass characteristics and it preserves sinusoidal signals. It is shown that sinusoidal signals are root signals of the filter. An upper… CONTINUE READING
