  • System and method for clock offset detection
    Patent number: 8446531
    Abstract: A system and method for detecting a sampling clock offset of an analog-to-digital converter used to digitize an analog image signal. A method comprises buffering samples of an analog image signal, computing a value of an autocorrelation function using the buffered samples and a delayed version of the buffered samples, and repeating the computing a value for delays in a range of delays. The method also comprises computing a sampling frequency offset from the values of the autocorrelation function and changing a sampling frequency using the sampling frequency offset.
