Abstract

PURPOSE: To enable to prevent spurious failure to other receivers, by providing unidirectional buffer amplifier at the prestage of the converter of TV receiver.
CONSTITUTION: The branch cable 9 branched from the branch line 30 is connected to the TV receiver 11 via the buffer amplifier 31 and converter 10 in each house 2. This buffer amplifier 31 is unidirectional broadband amplifier. Accordingly, various signals inputted via the cable 9 passes through the amplifier 31, and objective channel is selected with the converters 10A and 10B and delivered to the TV receiver 11. On the other hand, since unnecessary spurious is blocked which emitted from the converter 10A, for example, the spurious component can remarkably be reduced together with isolation of the branch path 30 and the failure by it can be prevented.
