1. A method for adjusting a signal at a receiver of a digital signal transmission system, comprising:

  • receiving an input data signal at a receiver of a digital signal transmission system;

    using the receiver, applying an offset compensation to the input data signal to generate an output signal;

    using a clock signal at the receiver, sampling the output signal to generate a plurality of data values and boundary values, each data value and each boundary value comprising either a high value or a low value based on the sampling of the output signal;

    detecting, by the receiver, a transition in value between two successive data values and determining a sampled boundary value between the two successive data values; and

    based only on the high or low value of the boundary value, adjusting by the receiver the offset compensation applied to the input data signal.
