Abstract

A method for reducing errors in electrographic digitizer systems where the horizontal and vertical coordinates are quantized at various time intervals. The method minimizes the time skew generated during quantizations and doubles the quantized coordinate pair output rate by utilizing a time-weighted linear interpolation.
