Abstract
In an engine speed sensing device, angle pulses produced when the crankshaft rotates through a predetermined angle are counted by a counter for a predetermined interval. The count of angle pulses is read into a central processing unit of a digital computer at the end of each set time interval in response to a control signal which both updates the angle pulse count and signals the processing unit to read the count.
