Abstract: PURPOSE:To exactly separate a stereo broadcasting and a voice multiplex broadcasting, etc., in a television signal converter at the reception side terminal equipment, etc., of a CATV system. CONSTITUTION:Respective first and second audio carrier signals FM modulated from a demodulating means 1 and the video signal of a base band are outputted, and these respective audio carrier signals are separated by a separation adjusting means 2.
