Abstract

PURPOSE:In the system in which multi-value transmission is carried out by distributing timing signal frequency within transmission band of information signal sample holding is performed at the point where multi-value pulse duration is stabilized. In this way, transmission is carried out under the state when identical phase combination is secured between information signal and timint signal.
