ABSTRACT:
A digital data decoder is provided that combines Viterbi algorithms and a run-length code constraint. The combined Viterbi detection and code constraint does not limit the bits that can be analyzed in determining the binary state of the bit currently being detected. The logic associated with the code constraint is not enabled unless actual data is being decoded.
