    Abstract: An integrating circuit for quantizing currents as small as 10 12 ampere is set forth. The over-all integrating principle is fairly conventional. However, a much simplified and improved charge removal technique and an electrometer-type operational amplifier having common-mode feedback for stabilization in the event of radiation damage substantially improves operation.

    Abstract: A system for converting an input AC signal into a output signal having a time period or duration proportional to the full-wave average value of the input signal. The system is formed of a pair of integrators, one of which is connected to accept a reference voltage, the other connected to accept a full-wave rectified version of the input signal. Both integrators operate for the same time, following which the voltage on one is fed to the input of the other so that the latter reversely integrates back to its initial or zero condition. The time required to perform the reverse integration is the desired time period.

    Abstract: An integrating analog memory circuit having a pair of switchable memory means for reading out memorized signals in one and combining with the new received signals for writing of the combined output into the other memory means, each input to the combining means being weighted, to detect a change by integration weighting means to detect a change in the mean energy level of new signals in a population of signals, many of which are varying as a result of amplitude modulation, and means for comparing the readout memory with the new signal to produce an alarm whenever the new signal exceeds the mean energy level of the memorized signal.
