ABSTRACT:
Control apparatus for an RLG dither motor includes a digital phase shifter for providing a clock signal related to the RLG position signal. A rate pulse generator for receiving an amplitude word signal generated by a processor at intervals determined by the clock signal and providing a pulse rate signal related to the amplitude word signal. The pulse rate signal is combined with the RLG position signal to provide a second pulse rate signal which is integrated to provide a triangular dither drive signal.
