ABSTRACT:
A biphase code detector and method for implementing the same. In accordance with one embodiment, the biphase code detector includes a receiver input for receiving a biphase encoded signal. The biphase encoded signal is a stream of unit bit cells each having a logic value encoded as a mid-bit transition between a first half-symbol signal component and a second half-symbol signal component. An integrated value is produced for the first and the second half-symbol components of a received unit bit cell. The biphase code detector further includes a delta detector that generates a difference signal corresponding to the difference between the integrated values of the first and second half-symbol components to determine the logic value of the received unit bit cell.
