摘要：
A device includes two electrodes (2, 3) positioned on a human body, two operational amplifiers (4, 6), an amplitude detector (5), a microcontroller (7) and a switchable frequency-dependent voltage divider (8) consisting of an upper shoulder (10) and of a lower shoulder (11). The microcontroller forms a high-frequency carrier signal at the output of a first input-output port (L), which signal is then fed to an inverting input of the first operational amplifier (4), in the negative feedback circuit of which the electrodes (2, 3) are positioned. The signal from the output of the first operational amplifier, after isolating the envelope in the amplitude detector, is fed to the input of the second operational amplifier (6), and is then fed from the output thereof to the input of an analogue-to-digital converter of the microcontroller. The second operational amplifier (4) and the switchable frequency-dependent voltage divider (8) form an active bandpass filter having an upper cutoff frequency determined substantially by the parameters of the upper shoulder of the switchable frequency-dependent voltage divider, and having a lower cutoff frequency determined substantially by the parameters of the lower shoulder of the switchable frequency-dependent voltage divider, wherein said lower shoulder of the switchable frequency-dependent voltage divider is formed by two circuits which are able to be connected to a zero potential via the microcontroller by means of an input-output port (M) or an input-output port (N). The frequency characteristics of such a filter, when connecting the port (M) to a zero potential, allow for registering a signal in a frequency band corresponding to the frequency band of a pulse wave signal the frequency characteristics of the filter when connecting the port (N) to a zero potential allow for registering a signal in a frequency band corresponding to the frequency band of a respiratory cycle signal.Le dispositif comprend deux électrodes (2, 3) disposée
