ABSTRACT:
A method for monitoring a digital channel is provided that includes several steps such as receiving an analog input signal corresponding to a digital signal, and equalizing the analog input signal to generate an equalized signal to a predetermined partial response target. The method further includes generating a pseudoternary signal from the equalized signal, and analyzing the pseudoternary signal to detect polarity alternation violations, as well as RLL global and interleave constraint violations.
