ABSTRACT:
Decoding unit for CMI-encoded input signals. A signal having 0/1 transitions is first derived from a signal. A 0/1 transition occurs in a CMI-signal as the result of encoding a binary zero or two consecutive binary ones. In the latter case the 0/1 transition is preceded two bits earlier by a 1/0 transition. By deriving a signal having 1/0 transitions, delaying this signal by two bit intervals and by comparing it to the first signal, the 0/1 transitions corresponding to a binary zero are then accurately detected. The resultant signal can easily be extended by one bit period, so that independent of any phase inversions of the read clock, the appropriate binary information is always generated.
