Abstract

PURPOSE:To generate multiplex signal of FM-FM system without time delay, by passing through a main carrier wave signal of angular modulation to a delay circuit having a delay characteristic so that the delay time can be changed according to the frequency by taking the frequency of a main carrier wave signal as the center frequency. CONSTITUTION:A modulation signal Fs and audio subcarrier wave signal Fsub from signal generators 61, 62 are applied to a signal synthesizer 63. The signal synthesizer 63 applies a synthesis signal FA superimposing audio subcarrier wave signal Fsub on the modulation signal Fs to a frequency modulation circuit 64. The frequency modulation circuit 64 frequency-modulates a main carrier wave signal F0 with the synthesis signal FA, and an FM signal FFM obtained is outputted via a delay circuit 65. The delay circuit 65 has delay characteristics where the frequency of the main carrier wave signal F0 takes as the center frequency and the delay time is changed according to the frequency.
