The possibility of a saving of bandwidth- or of transmitting additional information in a given bandwidth-by means of amplitude quantizing and time sampling is reviewed. The requirements on a tube to simultaneously time sample and quantize a video input, and to produce a residue output, are outlined. Beam deflection-type tubes were successfully built and tested which perform all of these functions...
A storage tube is described which maintains a bright visual display, using a charge pattern stored on an insulating layer to grid control the transmitted viewing beam. This insulating layer is a part of an image amplifier system, whose operation and characteristics are discussed. The factors affecting background uniformity and viewing duration have been investigated. Methods of extending the viewing...
