A motor and piston assembly is used to generate the output waveforms. A differential
pressure sensor is used to measure the pressure of the cuff. The pressure sensor is read
by a 16-bit differential Digital to Analog converter. The ECG output is performed by a 12-bit
Digital to Analog converter. A second 12-bit Digital to Analog converter is used to generate
the respiration waveform.
