Digitally controlled-operating system

摘要

A digitally controlled-operating system comprising a detecting means such as a speed sensor which generates pulses having a frequency corresponding to a detected value, an oscillation circuit consisting of a multivibrator which stops oscillation when the frequency of detected pulses from said detecting means exceeds a predetermined value while it maintains oscillation when the frequency is below the predetermined value, and a logical gate which opens and closes a gate in accordance with the output pulse signal from said oscillation circuit to control the on-off of said detected pulses from said detecting means, the digital operation being performed by the output signal from said logical gate.
