ABSTRACT:
A satellite receiving converter of the present invention performs receiving operation in response to a pulse signal supplied from a tuner. To prevent an amplitude of the pulse signal from being largely reduced in the receiving operation, the satellite receiving converter includes a trap circuit made up of an inductor and a capacitor. The trap circuit is provided after a low-pass filter which divides a pulse signal and a direct-current voltage supplied to a regulator IC. The trap circuit is provided so as to raise impedance with respect to the pulse signal at a signal input-output terminal, thereby preventing error operation of an internal circuit, such as a control circuit.
