Abstract
PURPOSE:To improve malfunction due to a noise or spurious, by performing sweepage setting a sensitivity switching circuit at low sensitivity at the time of performing a sweep operation, and performing the sweepage setting the sensitivity switching circuit at high sensitivity if no broadcasting station is detected. CONSTITUTION:When a state is set at a sweep operation state. a control circuit 24 outputs a switching signal S1 of H level first, and connects a resistor 19 between the input side of a high frequency amplifier circuit 2 and the ground, and decreases an input level to the high frequency amplifier circuit 2, then, performs the sweepage. When a signal with the a large level possible to be detected at a signal detection circuit 16 is received, the operation of a sweepage circuit 22 is stopped, and a state where the said broadcasting station can be received successively is set. Meanwhile, when no signal exceeding the preset level of the signal detection circuit 16 is received, the sweepage is performed by turning OFF a transistor 18 which constitutes the sensitivity switching circuit 17. In such a way, it is possible to prevent the malfunction due to the noise in the neighborhood of the detecting level of a carrier or the spurious of a ferroelectric field signal from being generated.
