Abstract

PURPOSE: To detect the numbers of revolutions at low and high speeds, while simplifying the construction, by constructing a system for integrating the pulses, which correspond to the numbers of revolutions, such that a circuit for discriminating the low speed is in series with a circuit for discriminating the high speed.
