ABSTRACT:
In response to a selected analog applied to the input terminal of an analog-to-digital converter, the digitized output signal is stored in a buffer/register. In making a comparison with a predetermined value, a second buffer/register stores either a preselected value or a second digitized signal. A comparator is coupled to the first and the second buffer/register to provide the result of a comparison. In this manner, the central processing unit is not involved in the comparison testing procedure.
