The second pulse detector receives the input signal in parallel with the first pulse detector, and processes the input signal using a second threshold, to thereby output a second signal having a second pulse waveform component, which corresponds to an interval in which a level of the input signal exceeds the second threshold. The determining circuit determines whether each of the first and second pulse waveform components conforms to the weak signal.
