<p>A direct current offset correction system is disclosed for use in an analog signal processing system. The offset correction system includes a comparator unit for comparing the polarity of signals from an analog signal channel and producing a binary output signal. The system also includes a digital accumulator unit that is coupled to the comparator output signal for providing an accumulated average signal over a predetermined period of time. The system also includes a threshold window digital comparator unit for determining whether the accumulated signal is within a defined threshold window of acceptable values. The system further includes a correction unit for applying a corrective signal to the analog signal channel.</p> |
