Abstract :
In this paper a circuit is developed which provides a train of uniform pulses logarithmically spaced in time. As applied to computing the system offers new methods for calculating products, quotients, powers, and roots. A pulse-interval error of less than one per cent (rms) was obtained with an experimental circuit.
