ABSTRACT:
If the timing of detection of an analog signal, by an A/D converter, with respect to its theoretical value is optimum, the most significant error bit output by the A/D converter will integrate to a zero value. The present invention takes the information indicative of the most recent history of amplitude variation of the analog signal to logically modify (affect polarity) the most significant error bit and apply it to an integrator. The integrated value is used to adjust a variable time delay clock circuit use in determining the detection time in the A/D converter.
