Abstract
A method and apparatus for level compensation is presented to compensate for signal level changes made by a signal processor. The original, unprocessed input signal and the output signal from the signal processor (e.g., an equalizer) are provided to a comparison unit which determines a difference in signal level between the two signals. The output of the comparison unit is provided to a level compensator along with the output signal from the signal processor. The level compensator then modifies the signal level of this output signal (e.g., matches it to the original, unprocessed input signal).
