出回路。In a pulse detection circuit that includes a sensor, a bandpass filter, and a comparator and detects the pulse rate from a part of the body, means for detecting the pulse rate is provided on the output side of the comparator, and the cutoff frequency of the bandpass filter is determined depending on the magnitude of the pulse rate detection circuit. A pulse detection circuit characterized in that it is configured to switch in a timely manner.
