  • Phase lock-loop modulator using an arithmetic synthesizer
    Patent number: 4021757
    Abstract: A phase lock loop has a phase modulator within the loop to produce an output signal of frequency shifted or modulated RF. The modulator is controlled by input signals via an arithmetic synthesizer.
    Type: Grant
    Filed: April 8, 1976
    Date of Patent: May 3, 1977
    Assignee: RCA Corporation
    Inventor: Edward Joachim Nossen
  • Accurate digital phase/frequency extractor
    Patent number: 3984771
    Abstract: Digital apparatus employing a direct frequency synthesizer for accurately measuring the phase difference between a received signal and a phase reference signal by calculating a coarse value based on the synthesizer's internal clock and subtracting therefrom a correction based on triangular relationships in the vicinity of the received signal's actual zero crossing point.
