A multiple rate discharge circuit is disclosed for application, for example, to an integrator connected to a radiation detector as used in computerized axial tomography. The integrator is charged for a given time and then allowed to discharge at a first, relatively slow, rate for a predetermined time. If, at the expiry of the predetermined time, charge remains in the integrator, the discharge rate is considerably increased. The second-mentioned discharge rate is preferably about eleven times faster than the just-mentioned rate, and the two rates are achieved by the selective connection of resistive discharge paths to the integrator.
