Abstract

PURPOSE:To demodulate a subcarrier by applying frequency conversion to a sound subcarrier to record the result by a conventional recorder thereby applying frequency conversion to an input signal from the recorder and reproducing the second subcarrier. CONSTITUTION:A sound subcarrier applying PSK modulation to a PCM signal is fed to an input changeover switch 15 of a receiver and the subcarrier is recorded on a recorder, then the switch 15 is changed over to the position of an amplifier 16. A mixer 17 applies frequency conversion to the subcarrier of a prescribed frequency from the amplifier 16 by using a frequency from a local oscillator 20. The subcarrier subjected to frequency conversion from the mixer 17 is amplified (18), outputted to an output terminal 19 and recorded by a conventional recorder. Then the input signal from the recorder is fed to an input terminal 21 and the switch 15 is switched to the position of an amplifier 24. Then the input signal from the terminal 21 is amplified (22), fed to a mixer 23, the subcarrier is demodulated by a signal from the oscillator 20, the subcarrier is amplified by the amplifier 24 and outputted via the switch 15.
