ABSTRACT:
The present invention relates to a satellite television broadcasting receiver which receives waves from a satellite, selects a broadcasting channel and obtains an FM demodulated video signal by passing a selected signal through the band-pass filter. In this satellite television broadcasting receiver, the video signal superposed with a large energy dispersion signal is inputted to the first clamping circuit at a low level, to eliminate the energy dispersion signal. Thus, a room is provided in the dynamic range of the amplifier at the later stage and the DG and DP of the amplifier at the later stage are maintained at a satisfactory level by the second clamping circuit. As a result, even in the case of a satellite television broadcasting in which the level of the energy dispersion signal superposed on the video signal is large, distortion which occurs due to the nonlinearity of the amplifier can be reduced substantially so that the image can be reproduced on the screen in a satisfactory condition without an interference of flickering.
