Abstract
An apparatus for counting stacked sheet-like materials having low or ambiguous contrast characteristics associated with their edges. A single non-pitch matched sensor is used to synthesize sensor output data that is the equivalent of that generated by pitch matched single or plural sensors. Automatic correction for errors in pitch match of the sensor and automatic velocity determination are provided. Sensor signal synthesis is accomplished through use of a multiple output tap analog delay line functioning as a discrete time processor.
