Abstract

Abstract A multiplexer for allowing multi-octave processing of sampled data by means of a common single-octave data processor. Sampled data is preselectively delayed, corresponding to delay-coding thereof, and a multiplex switch samples the progressively delayed delay-coded data at progressively reduced data sampling rates, corresponding to lower octaves of interest. In this way the several octaves of data are interleaved or time-multiplexed. Similar multiplexing within the single-octave data processor corresponds to frequency multiplexing of the time-multiplexed multi-octave data, whereby the single bandwidth limit processor may handle such multiple-octave data.
