ABSTRACT:
A system and method for extracting a data signal transmitted by a signal source encoding the data signal onto first and second binary signals as a known two-bit binary state of the two signals taken together includes memory storing single bit binary patterns representative of known bit pattern and a reference table of two bit binary state couples representative of a data signal bit encoded onto the first and second binary signals. A processor monitors one of the first or second binary signals and compares the one monitored binary signal to the stored single bit binary patterns in memory. The processor stores, if a match is found, the respective binary states of the first and second binary signals in memory as a pair of two bit binary states. The processor then compares the stored pairs of two bit binary states representative of the first and second binary signals against the stored reference table of two bit binary state couples, and stores in memory a binary code representative of the encoded data signal bit represented by each such match.
