SATELLITE BROADCAST RECEIVER

摘要

PURPOSE:To eliminate spurious radiation generated from a satellite broadcast receiver. CONSTITUTION:On/off of a frequency division circuit 5 supplying a clock to a satellite broadcast signal processing part 2 in the satellite broadcast receiver 1 is performed by using a gate 6. The gate 6 controls the supply of the clock by the control signal of an interface 4 receiving the control signal from an external controller 8. Thereby, the operation of the satellite broadcast signal processing part 2 and that of an output buffer can be controlled. When no satellite broadcast receiver 1 is used, the output buffer 3 that is the main cause of the spurious radiation to affect the signal processing part 7 of a television or video can be stopped without using dedicated power source switch and control system.
