Abstract
A compensation circuit is configured to compensate for a loss of low-frequency signal content of an input signal at a receiver input. The compensation circuit includes a switching circuit and a summing circuit coupled to the switching circuit. The switching circuit is configured to receive a first plurality of digitized values sampled from a receiver output signal. The summing circuit is configured to generate a summation signal based on a combination of a first plurality of input values selected by the switching circuit. The selecting is based on the first plurality of digitized values. The compensation circuit is configured to provide to the receiver input a compensation signal to compensate for the loss of the low-frequency signal content from the input signal. The compensation signal is based on the summation signal and is a function of at least one gain value.
