PURPOSE:To always connect an FM detecting signal to an input toward a BS decoder in a satellite broadcasting reception system. CONSTITUTION:When the FM detecting signal of CS broadcasting is inputted, dispersal is reduced less than 600kHz by a dispersal removing circuit 5. Emphasis is loaded by an emphasis circuit 6, and the signal is passed through an amplifier circuit 8 and supplied from an FM detecting signal output terminal 9 to a BS decoder. When the FM detecting signal of BS broadcasting is inputted, the signal is supplied through a switching circuit 2, switching circuit 7, amplifier circuit 8 and FM detecting signal output terminal 9 to the BS decoder.
