ABSTRACT:
A method and apparatus for demodulating biphase-encoded signals is disclosed. A digital phase-locked loop produces a clock signal which is in phase with the clock signal of the biphase-encoded input signal. The clock signal from the phase-locked loop is then used to derive the data signal from the biphase-encoded input signal in a manner which enhances tolerance to edge skewing.
