Abstract
A delta modulator for a heart pacer which not only allows sensed signals to be monitored, but also facilitates measurements of DC operating potential levels. The DC levels, and changes in them, can be measured accurately by equilibrating the modulator with the application to it of a suitable reference potential as the initial step in a measurement sequence. This same technique allows small signal variations to be tracked even if they are superimposed on large signals.
