THE RESOLVER, A CIRCUIT FOR REDUCING THE COUNTING LOSSES OF A SCALER

Abstract

The resolver is a circuit that reduces the counting losses of an ordinary scaler by storing up most of the pulses that otherwise would be lost in dead time, and releasing them uniformly at a safe rate for the scaler. Even for very short input pulses, the circuit contains no active elements that need to be fast enough to follow these pulses, and is thus simpler than an equivalent fast scaler. In a typical case the maximum permissible counting rate of the scaler is raised by a factor of the order of 30. The counting losses of such a circuit are computed. A detailed circuit and the results of tests on it are shown.
