Abstract

PURPOSE:To perform stable side-band communication, by transmitting one wave of pilot signal taking a crystal oscillator of conventional stability as an original source, comparing the phase of a signal having the same frequency as the pilot signal and of the pilot signal, controlling the local signal oscillator, and by taking synchronism.
