Abstract
The theory for the replacement of a series of taps having small sbengths with a single larger tap while maintaining filter selectivity is presented. This technique works for the general class of bandpass fiiters, including broad-band fiiters with low shape factors, where withdrawal weighting is ineffective. This tap enhancement procedure increases tap weight accuracy and reduces diffraction distortions by removing small taps. Experimental results for capacity weighted transducers verify the theory.Keywords
