Abstract
An improved electronic integrator enabling compensation or correction for the error in integration due to inherent dielectric absorption in the integrating capacitor. A sampling amplifier samples the error during a sampling interval and develops a correction voltage representative of the error. During the next sequential integration interval the correction voltage is transferred to the integrating capacitor to counteract and thereby compensate for dielectric absorption in the integrating capacitor. Timed control means provide the sequential timing and operation of the apparatus.
