Abstract
A physiological signal detection system is disclosed. The physiological signal detection system includes a measurement module, a signal processing module, and a microcontroller. The measurement module measures a subject in a non-contact manner to obtain a frequency modulation signal. The signal processing module is electrically connected to the measurement module, and the signal processing module includes a Mohr discriminator, which is used to demodulate the frequency modulation signal to obtain a physiological signal. The microcontroller is electrically connected to the signal processing module for converting and obtaining a digital physiological signal.
