ABSTRACT:
An incremental integrator integrates a signal from a previous time to the present time to obtain an average value for the signal. An input signal is applied to an analog integration circuit which performs a continuous integration of the input signal. A time delay circuit delays the output of the integration circuit for a time period equal to that of a sampling clock. The output of the delay circuit as well as the output of the integration circuit are applied to a differential amplifier. A sampling circuit samples the output of the differential amplifier so as to give a value equal to the integral for a period equal to the delay circuit period at the time the signal was sampled.
