Abstract
To provide for digital storage of a command signal commanding a predetermined speed of the speed control system, a digital counter is provided forming a memory, connected to an analog-digital converter to generate a derived command signal in dependence on the counted state of the counter. Stray signals which may affect the count state of the counter thus can only change the time at which the counter reaches its predetermined count state, and not the count output thereof, whereas such stray pulses might otherwise affect the command signal. The counter holds the commanded speed as a count number.
