Abstract
Eye violation detectors which provide either one of a "graded" or "half-graded" eye violation indicator technique. More particularly, the eye violation detector for practicing the "graded" technique provides an eye violation region in one or more eyes of a multiple eye pattern which is uniformly disposed on either side of the center of each of one or more eyes of the multiple pattern and includes a different amplitude in each of the eye patterns of interest. The eye violation detector for practicing the "half-graded" technique provides an eye violation region in one or more eyes of a multiple eye pattern which is disposed on only one side of the center of each of one or more eyes, except for the center eye of the multiple eye pattern, and includes a different amplitude in each of the eye patterns of interest.
