Abstract
A sorting apparatus wherein a plurality of first and second electrical color signals from a predetermined number of viewer elements are sampled by a time multiplexer, classified on the basis of the ratio of the color signals sampled from each viewer, and demultiplexed to actuate an ejector associated with each viewer if a comparison of the ratio classification signal with predetermined references indicates an unacceptably colored product or foreign object is characterized by circuitry for testing the digital logic elements associated with the sorting apparatus, and for sampling and displaying signal outputs from predetermined test points within the sorter circuitry at predetermined multiplex times.
