  • Variable rate digital controller for a frequency synthesizer
    Patent number: 4270117
    Abstract: Variable rate digital control of a frequency synthesizer is afforded by periodically generating a digital signal from among a plurality of such digital signals representative of various tuning rates, converting each digital signal to a digital control word through a rate decoding means in which each control word is associated with at least one of the digital signals, applying the control words to a digital counting means having a plurality of counting rates, with each rate being determined by a different one of the control words, and applying the digital count of the digital counting means to the frequency synthesizer to control its frequency.
