ABSTRACT:
In one embodiment of the present invention, a method for adjusting a signal includes applying a plurality of compensation for distortion to a signal to generate an output signal. The method also includes, using a clock signal, sampling the output signal to generate a plurality of data values and boundary values, each value comprising either a high value or a low value based on the sampling of the output signal. The method also includes detecting a transition in value between two successive data values and determining a sampled boundary value between the two successive data values. The method further includes based at least on the high or low values of the boundary value and a plurality of data values before or after the boundary value, independently adjusting each compensation applied to the signal.
