In one embodiment of the present invention, a method for adjusting a signal includes applying loss compensation for frequency-dependent distortion to a signal before or after the distortion occurs 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 further includes, based only on the high or low values of one or more of the data values and boundary values, adjusting the loss compensation applied to the signal, where if the loss compensation applied to the signal is to be increased, the loss compensation is increased by a first amount, if the loss compensation applied to the signal is to be decreased, the loss compensation is decreased by a second amount, the magnitude of the first amount is not equal to the magnitude of the second amount, the first amount and the second amount are associated with a control target value, and the control target value is adjusted dynamically based on the value of the loss compensation applied to the signal.
