Abstract
An all-electronic device for removing distortion from start-stop teletypewriter signals is described. The circuit utilizes a sine wave oscillator for timing and binary counters for synchronization. It provides low output distortion, high tolerance to input distortion, hit-reduction, transmission of steady-space break signals, and regeneration of one element-length of stop time. It features quick change of speed and code, use of office battery power, and reduction of routine maintenance to one adjustment. Over a year´s experience has been obtained with about 100 of these units.
