摘要： In a multiplex signal processing apparatus, in the band of a demodulated signal in which a carrier is amplitude-modulated in a vestigial side band by a main signal, another carrier is superposed which is identical in frequency to the first carrier but different in phase by 90.degree. is amplitude-modulated its double side bands by a multiplex signal which is different from the main signal and which is formed into a vestigial side band signal by a nyquist filter. At least either the frequency or polarity of the multiplex signal is inverted on the transmission side by a multiplier, an oscillator and a filter. At least either the frequency or polarity of the multiplex signal is inverted on the reception side by a multiplier, an oscillator and a filter. The reception side has a crosstalk reduction filter for removing crosstalk from the main signal to the multiplex signal.
