Abstract

PURPOSE:To secure a constant average value for a timing signal by giving a 1-time slot delay for the output of a conversion code generator and then comparing the output with the code given from an encoder, and thus to carry ut a code transmission by utilizing a transmission path code capable of monitoring a circuit error.
