Abstract
A method of processing a time-varying output signal from a photosensor is provided. The time-varying output signal corresponds to a plurality of marks or indicia on a recording medium moving into and out of a field of view of the photosensor with the marks having been printed on the recording medium by a printing system. The method includes amplifying the time-varying output signal from the photosensor; converting the amplified time-varying output signal from the photosensor to digitized data points using an analog to digital converter; and averaging a plurality of the digitized data points.
