DATA PROCESSING DEVICE AND SYSTEM

원문 (중국어)

A data processing device is provided, including a spectrum extraction circuit configured to receive a first electrode signal and obtain a first component signal having a first preset frequency in the first electrode signal; an amplitude and phase extraction circuit, electrically connected to the spectrum extraction circuit, configured to generate a differential phase-shift keying signal, the differential phase-shift keying signal includes a real part of phase and an imaginary part of phase of the first component signal; a demodulation circuit, electrically connected to the amplitude and phase extraction circuit, configured to demodulate the differential phase-shift keying signal according to a phase angle to obtain data information in the first electrode signal, the phase angle is an arctangent value of a ratio of the real part of phase to the imaginary part of phase.
