An improved process of extraction of uranium from phosphoric acid and in particular uranium VI from phosphoric acid especially strong phosphoric acid using a selective synergistic extractant mix of an organo-phosphorous acid and a neutral extraction agent. The desired feature prior to being printed is masked by various decimation filters and the decimation is performed at various pitches. A retiming circuit reads the stored samples and, based on first portions of first and second timing portions of the sector, determines phase adjustments.
