1. A data transmission system comprising:

  • a. a coding unit coupled to a communication channel, that transmits encoded digital information having defined minimum and maximum durations of logical states “

    low” and



    high”

    ;

    b. a decoding unit coupled to the communication channel, that decodes information received, the decoder comprising;

    i. a free running local oscillator LO coupled to an array of sampling capacitors, that effectively samples the information using the LO frequency, and ii. a circuit coupled to the sampling capacitors, that decodes the information and corrects any mismatch between nominal and actual LO frequency.
