Abstract

PURPOSE: To simplify the constitution of a signal processing circuit by converting an information signal and additional information signal into frequency-modulated signals in difference frequency bands and then by recording those frequency-modulated signals on a recording carrier together.
CONSTITUTION: Coded acoustic signal 21 is frequency-modulated by the 1st FM modulator 33 and by way of BPF34, the frequency-modulated signal is changed into the 1st frequency modulated wave 35, which is applied to adder 39. To the other input terminal of adder 39, the 2nd frequency modulated wave 38S obtained by frequency- modulating address signal 16 by the 2nd FM modulator 36 and by passing the frequency-modulated signal through the 2nd BPF37 is applied, and the addition output of the 1st and 2nd frequency-modulated waves is passed through amplitude limiter 40 to obtain frequency-division multiple waves 41S, which are recorded on carrier 26 being amplified. As a result, there is no need for time-axis compression and expansion to insert an additional signal, so that the constitution of the signal processing circuit can be simplified.
