Abstract
A circuit for monitoring the alignment of analog-to-digital converters. The digital output signal from a converter under test is separated into positive and negative component signals which are compared by a subtraction circuit. A difference signal is then generated by the subtraction circuit to represent the required converter adjustment. Also included are adder circuitry for a sum output and provisions for analog display.
