Abstract: CHARACTER RECOGNITION SYSTEM A character recognition system including a timing subsystem, comprising a base oscillator or clock, and timing circuits driven by the base clock to provide a plurality of timing pulses for timing the operation of the entire system. The timing circuits are governed in part by delay circuits which are in turn controlled by the amplitude and location of peak signals derived from scanning earlier pulses. EN978027
