Abstract: Techniques to determine and indicate the extent to which transitions of an input signal deviate from a desired transition region. In an implementation, an indication may be provided when a transition of an input signal occurs within the desired transition region and an indication may be provided when a transition of an input signal occurs outside the desired transition reagion. In an implementation, a difference between a number of times when input signal transitions occur inside and outside of the desired transition region may be provided. Accordingly, a receiver of the input signal may decide whether to ignore or use the input signal based on the difference between a number of times when input signal transitions occur inside and outside of the desired transition region.
