Abstract

A multi-level band-restricted waveform generator in which a modulation wave prior to band restriction (M-level signal sequence) is broken into elementary waveforms and a plurality (N-nary) of prestored waveform components corresponding to the elementary waveforms after predetermined band restrictions are read out of a read-only memory for generating waveform components and added to generate a desired multi-level band-restricted waveform.
