Abstract
A DC offset correction loop (200, 300) utilizes a peak estimator (218, 322) to determine peaks associated with a digital signal (238, 338). The peak estimator (218, 322) averages the peaks in order to estimate the DC offset. A summer (216, 326) sums the DC offset (242, 350) with the digital signal to produce a corrected output.
