| description | A digital demodulator for use with a Highway Addressable Remote Transducer (HART) modem is provided. Analog input signals are digitized according to a sampling clock rate to produce a discrete time signal. Filtering and edge detection allow determinations of "mark" or "space" data in a demodulated signal in conjunction with analyzing a detected signal period, a cycle period, count histories and/or an on/off signal period. |
