78ELECTRICAL NOISE OR RANDOM WAVE GENERATOR


DEFINITION

Classification: 331/78

(under the class definition) Subject matter wherein the oscillator comprises means for utilizing the random translatory motions of charged particles for generating a substantially infinite number of waves of different frequencies which are fortuitously related, having no definite phase relationship, period, amplitude or shape. The means may be (1) a solid conductor, the random waves being generated by the thermal agitation of the free electrons, or (2) a thermionic space discharge device, wherein the random waves are caused by random emission of electrons (such as the shot effect in a temperature limited thermionic diode), or (3) a gaseous space discharge device wherein the thermal agitation or electrical excitation of the molecules, ions and electrons of the gas produces the random waves.
