ABSTRACT:
A method and apparatus for digitally decoding a biphase encoded transmission signal, which combines both clock and data signals with a high degree of noise immunity. The decoding method has a skew tolerance nearly equivalent to using conventional decoding methods with twice the sampling rate. The method utilizes a unique look-ahead feature to resolve otherwise ambiguous signals.
