ABSTRACT:
An apparatus for producing a frequency-multiplex signal on the basis of a plurality of signals so as to record the produced frequency-multiplex signal on a recording medium, second signal having a frequency lower than that of the first signal. The apparatus includes a multiplying circuit for multiplying the frequency of the second signal by 2 and an amplitude-modulator for multiplying the first signal by the output signal of the multiplying circuit. Also included in the apparatus is an adder for adding the second signal to the output signal of the amplitude-modulator, the output signal of the adder being recorded as the frequency-multiplexing signal on the recording medium.
