Abstract

PURPOSE: To prevent waveform distortion by providing a circuit, which compensates amplitude attenuation dependent upon the receiving-side sound trap, in the transmission side in the system where band-compressed sound signals or multilevel PCM signals are transmitted in stead of picture signals.
CONSTITUTION: Sound signals or multilevel PCM signals inputted from input terminal 9 have only amplitude distortion, which is generated in sound trap circuit 7 in the receiving side, compensated by amplitude compensation circuit 10 and are outputted to switch 11. In switch 11, video signals from terminal 1 and band- compressed sound signals or multilevel PCM signals from terminal 9 are switched according to purposes and are transmitted to the receiving side.
