ABSTRACT:
A digital voltage accumulator functioning to store a digital signal over an extended period of time, the digital signal representing the accumulated sum of values of an analog input signal as sampled during the period of time following system reset command. The accumulator is capable of selectively incrementing or decrementing the stored signal, following an update command, in response to amplitude and polarity changes in the analog input signal. Signal storage is effected using a digital counter and a bipolar digital to analog converter. The analog equivalent to the stored digital signal is arithmetically summed with the analog input signal. Update is accomplished by comparing this summed signal with the analog equivalent of the stored digital signal upon command. The digital counter increments when the sum signal is positive relative to the stored signal and decrements when the sum signal is negative relative to the stored signal. The update cycle stops when the comparator senses that the stored digital signal equals the arithmetic sum of the analog input signal plus the old value of the stored digital signal.
