Displays numeric characters 1 through 7 on cathode-ray tube by deflecting spot to trace out each character continuously. X and Y defection voltages are obtained by combining sine and cosine terms of first five harmonics of 30-kc fundamental. Transistorized gated oscillators, flip-flop serial counters, and emitter -followers feed 10 toroidal transformers having one sot of secondary windings for each character.-K. E. Perry and E. J. Aha, Generating Characters for Cathode-Ray Readout, Electronics, 31:1, p 72-75.
