An overview of the channelization function, the parallel signal processing techniques used in channelizers, the signal processing functions, and the critical channelizer parameters is given. Signal processing capabilities that use analog techniques s
This report describes the test and evaluation of the Magnetostatic Wave Channelizer (MSWC). The MSWC was developed for Electronic Warfare (EW) systems and applications. The motivation for MSWC resulted from a need for wide instantaneous bandwidth and
