ABSTRACT:
A method of producing a correction signal includes receiving a predetermined data sequence (500). The data sequence is sampled at predetermined times, thereby producing a sampled data sequence (522, 532). The sampled data sequence is separated into first and second sampled data sequences. A ratio is calculated (550, 558) from the first and second sampled data sequences. A correction signal is produced (556, 564) in response to the ratio.
