Filter for heartbeat signal
WebThe signal waveform is analyzed by taking 80% of the max values of the digital signal being accepted, and then uses a peak detector function to detect these peaks of the signal. … WebThe heart beat at rest was measured to be 75 bpm, and 137 bpm after five minutes of intense exercise. ... At a frequency of around 60 Hz, the signal reaches its lowest voltage. The filter is successful in removing 60 Hz noise to an unnoticeable voltage of 0.01 V and providing a gain of 1, since the input voltage is .1 V.
