Abstract
Self-calibration of a digitizer is carried out by using a square-wave test signal which is digitized by the digitizer, and temporal positions of the digitized values output by the digitizer are compared to respective reference periods of the test signal. The results of the comparison operations are then used by a microprocessor to calculate a time delay for adjusting a clock signal supplied to the digitizer.
