ABSTRACT:
A circuit for processing the a.c. output of a tachogenerator whose frequency is proportional to the speed of a rotor of the tachogenerator, said circuit including voltage level detection means responsive to said a.c. output, key pulse producing means responsive to at least one output of the detection means to produce a key pulse whose duration is inversely proportional to the rotational speed, first gating means responsive to an output of the detection means and an output of the key pulse producing means to produce a reset pulse after a predetermined period in the interval between each key pulse, and a voltage generator responsive to each reset pulse to provide a predetermined output level and responsive to each key pulse to ramp that output level at a predetermined rate for the duration of that key pulse, whereby the output level of the voltage generator during each said predetermined period is a predetermined function of the rotational speed.
