Abstract
PURPOSE:To securely decide the reception of a FM-CHIRP signal by providing an input signal OR circuit, a lever peak channel detection signal OR circuit, and a FM-CHIRP signal detecting circuit. CONSTITUTION:The input signal OR circuit 10 is connected to output lines from a quantizing circuit 5 to detect whether or not the output of a quantized signal from each channel is present. Further, the level peak channel detection signal OR circuit 11 is connected to output lines 7 from a channel selecting circuit 4 to detect whether or not there is the output of a level peak channel detection signal. Then the FM-CHIRP signal detecting circuit 12 inputs the output signal of the circuit 10 and the inverted signal of the output signal of the circuit 11 to a signal showing that the FM-CHIRP signal is detected to an output line 13 when the quantized signal is outputted (the output signal of the circuit 10 is '1') and when the level peak channel detection signal is outputted (the output signal of the circuit 11 is '0').
