INSTALLATION AND METHOD FOR SEPARATING THE NOISE FROM THE HEARTBEAT SIGNAL OF THE SENSOR

摘要

PURPOSE: An installation and a method for separating a noise from a heartbeat signal of a sensor are provided to measure heartbeat in real time by detecting heartbeat of a moving examinee in real time. CONSTITUTION: A band-pass filter(100) is divided into at least more than one different frequency bands and performs filtering. The band-pass filter pass at least more than one high frequencies which are different from each other. An envelope detector(200) restores high frequency signals into a signal with a basic period of heartbeat. A common pulse generator(300) extracts the heart beating signal. An edge signal sensor(400) senses an edge signal of a pulse signal and calculates heart rate.
