and off states of this bypass line and turning on and off the dc power to the amplification circuit 14 the switch element is switched on and off in accordance with the manual operation or the like on the switch operation section 17 as shown in fig1 for example while the bypass line is in the on state the dc power to the amplification circuit 14 is off so that the broadcast signal is not amplified thereby meanwhile while the bypass line is in the off state the dc power to the amplification circuit 14 is on so that the broadcast signal is amplified thereby the mixer 15 is constructed using an inductor and a capacitor for example the output terminal of the ac dc converter circuit 11 is connected via the inductor to the terminal through which the mixture of the dc power and the broadcast signal is outputted whereas the output terminal of the amplification circuit 14 is connected via the capacitor to the terminal through which the mixture of the dc power and the broadcast signal is outputted this contributes to avoiding influence of unwanted ac components on the operation of the ac dc converter circuit 11 and influence of unwanted dc components on the operation of the amplification circuit 14 returning to fig1 the structure of a splitting section in the television receiver 20 will now be described below the television.
