Abstract

PURPOSE:To enable to perform good reception, by controlling that the intermediate frequency is almost in agreement with the center frequency of the intermediate frequency filter through the detection of the pilot signal and excluding the cross talk between the two signals to the utmost with a simple constitution. CONSTITUTION:The frequency control circuit which is controlled for the output signal of the pilot signal detector 8, consists of the mixer 3, intermediate filter 5, amplitude limiter 6, frequency detector 7, analog signal gate 16, and LPF15 and local oscillator 14, and frequency control operation is made only when the pilot signal is included in the multiplex signal transmitted, and the intermediate frequency is controlled to the center frequency of the filter 5 even with imcomplete tuning operation more or less to minimize the cross talk.
