Abstract

PURPOSE: To provide a means to reproduce the input signal in good fidelity by keepintg phase change to the ratio of 2/μ against the maximum variation of the single polartity signal, as the phases of the carrier wave is amplitude modulated against the single polarity signal like the facsimile signal which contains a meadium tone.
