Abstract
The present invention relates to apparatus for generating electric signals. Basically, the disclosed apparatus comprises a cathode-ray-type tube wherein the electron-beam sweeps across an especially designed electron-receptor. By suitable design of the receptor in conjunction with the beam-deflecting signal, the disclosed apparatus generates many desired output signals.
Claims11
In combination with a cathode-ray tube having means for producing an electron beam, means for deflecting said electron beam, and a collector electrode for collecting the electrons of said electron beam, the improvement comprising:
- a resistance configurated electron receptor positioned to be impinged upon by said electron beam as said electron beam is deflected by said deflection means;
- the resistance of said resistance-configurated electron-receptor varying longitudinally along the area presented to the electron beam, being adapted to produce an output signal corresponding to a desired waveform;
- said electron-receptor being a unitary structure of resistive material, having a front surface onto which said electron beam impinges, and having a back surface;
- the front-surface/back-surface direction defining the longitudinal direction of said electron-receptor;
- the entire back-surface of said electron-receptor being in electrical contact with said collector-electrode.
