Abstract

A digital wave filter operating on bandpass sigma-delta (SD) modulated signals is presented in this paper. The filter is obtained by a z-domain transformation of a baseband SD domain filter which is a binary-quantized discrete model of an analog distributed parameter filter (ADPF). Thus, the design properties of various ADPFs can be utilized for constructing the presented type of digital filters. A single-flux quantum filter circuit built of superconductive Josephson junctions was found to have a potential to operate at 10GHz by circuit simulation.
