ABSTRACT:
A reliable, low cost system for generating precisely aligned pixel clock and index signals for a digital scanning or printing system is based on a novel single channel encoder pattern detected with a single sensor. The signal output of the sensor representing the encoder pattern is processed with phase locked loop based circuit to generate pixel clock and index signals of known and guaranteed phase.
