Abstract

PURPOSE:To ensure an assured and proper operation for the frequency shift detecting circuit in the SSB receiver by determining the basic wave frequency in the spectrum of the demodulated aural output and deciding the carrier center of the transmitter side at the point where the frequency of the modulating time is zero.
