AN EXPERIMENTAL DEVICE FOR CODING AND INTRODUCING ELECTRIC SIGNALS INTO COMPUTERS (EKSPERIMENTALNAYA USTANOVKA DLYA KODIROVANIYA I VVODA ELEKTRICHESKIKH SIGNALOV V EVM),

The use of general purpose memory-containing electronic computers permits the storage of information over the necessary periods of time and the processing of signals according to any required algorithms. Such computer use for the processing of electrical signals necessitates the design and construction of special devices for signal-to-code conversion and the introduction of such a code into the computer. The present article describes an experimental device which converts electrical signals into the binary code. It uses a special coding tube with a plane two-dimensional beam the scanning frequency of which may be promptly varied within the 0 to 33 kc range. This is important because the scanning speed determines the spectral width of the processed signal. The tube, indicator-amplifier, scanning pulse generator, and forming and cyclic code units are described. A discussion is given on the cyclic-to-direct code converter, the output direct code pulse shaper, direct code indicator, decoder, and decoded signal indicator.
