Abstract
An output circuit for a digital physiological measuring instrument. The output circuit provides means for a digital signal indicative of a physiological parameter to operate on an excitation signal from a monitor to provide a response signal for driving the monitor to generate a visual display of that parameter. The excitation signal is scaled in a digital-to-analog converter, corrected for a zero offset of the digital signal, and then applied to the monitor. A dummy excitation signal is provided to enable the output circuit to drive a readout device having an analog input but not providing an excitation signal.
