Abstract
An FM receiver includes a first antenna and a second antenna. A first pulse generator produces a first pulse according to a noise signal included in the signal received by the first antennas, and a second pulse generator produces a second pulse according to a noise signal included in the signal received by the second antennas. A calculation circuit including shift registers is provided for shifting data, which is either one of the first and second pulses, in one direction in accordance with the first pulse from the first pulse generator and for shifting the switch data in another direction in accordance with the second pulse from the second pulse generator. Also, a switch circuit is provided for switching on a transmission line for a signal received at either one of the first and second antenna in response to the data produced from the calculation circuit.
