  • Method and system for frequency synchronization
    Patent number: 8913632
    Abstract: Systems and methods of synchronizing the frequency of a slave clock to that of a master clock using time-stamps in transmissions from a master device having the master clock, determining an error signal, and adjusting the frequency of the slave clock based on said error signal.

  • Amplifier with a universal automatic gain control circuit
    Patent number: 6995806
    Abstract: An amplifier (125) includes a gain stage (210) for amplifying a signal received by the amplifier (125). The amplifier (125) also includes an AGC circuit (400) that adjusts the amplification of the gain stage (210) and that includes a comparator (440) for determining whether the input signal is one of a digital pilot signal and one of an analog pilot signal. The AGC circuit (400) processes both digital and analog pilot signals and automatically adjusts the processing method depending upon the type of pilot signal.

  • Frequency agile adaptive automatic gain control circuit
    Patent number: 6567118
    Abstract: An amplifier (125) includes at least one gain stage (210) for amplifying a signal received by the amplifier (125). The amplifier (125) also includes an AGC circuit (400, 500) that adjusts the amplification of the gain stage (210). The AGC circuit (400, 500) determines whether the input signal to the amplifier (125) is a digital signal or an analog signal and transforms either signal into the frequency domain, thereby automatically adjusts the processing method depending upon the type of pilot carrier signal. The AGC circuit (400, 500) also possesses the ability to process a change in the frequency of a pilot carrier signal remotely.
