<P>PROBLEM TO BE SOLVED: To provide a system for removing a DC offset component from an input signal. <P>SOLUTION: The system includes a sorter for separating positive samples and negative sample of the input signal. The system further includes a positive sample average generator for calculating a positive sample average according to the number of positive samples in the input signal, and a negative sample average generator for calculating a negative sample average according to the number of negative samples in the input signal. A balanced average generator is provided for receiving positive and negative sample averages from the positive and negative sample average generators and for generating a reference signal. The system further includes a subtractor for subtracting a reference signal from the input signal to generate a DC-offset compensated output signal. <P>COPYRIGHT: (C)2011,JPO&INPIT |
