  • Speed measurement system with means for calculating the exact time period of a known quantity of speed pulses
    Patent number: 4434470
    Abstract: A digital speed measurement circuit for an engine includes a magnetic pick-up positioned adjacent an engine-driven gear having a substantial number of teeth so that the pick-up produces a number of speed pulses per revolution of the gear. These pulses are shaped into square waves by a signal conditioning circuit and connected through a synchronizing circuit which responds to the trailing edge of each square wave to produce a triggering pulse, with each triggering pulse supplied to a tooth counter. A high speed clock is connected to a second counter which is reset with each triggering pulse. Sampling pulses are produced in an associated control system which is not coordinated with the speed pulse but which are longer in duration than any of the speed pulses and which control the flow of tooth counts to the tooth counter.
