Abstract

1,057,767. Cathode-ray tubes. STANDARD TELEPHONES & CABLES Ltd. May 29, 1964 [June 3, 1963], No. 22300/64. Heading H1D. [Also in Division G4] In a digital microphone sound impinges on a diaphragm 1 carrying a magnet 9 to correspondingly deflect a line electron beam across a coded grid to produce digitally significant patterns of markings on output target electrodes. Any code, such as pure binary or cyclic binary, can be used and the target electrodes can be scanned sequentially to provide a serial read-out for use in a pulse code modulation system.
