Abstract :
A novel median-type filter, the linear median hybrid (LMH) filter with switched-capacitor subfilters, is presented. In the LMH filter, median operation is applied to the outputs of a few linear subfilters. Thus the implementation of the LMH filter is simple as compared to a standard median filter with approximately the same noise attenuation. The circuit was implemented with GaAs MESFET technology.<>
