Class Information
Number: 331/104
Name: Oscillators > Transit time oscillator
Description: Subject matter wherein the oscillator comprises an electron tube, having input and output electrodes, and a frequency determining network effectively coupled between the output and input electrodes and wherein the electrode spacing or the electrode biasing potentials, or both, are so chosen that the time of flight or transit angle of the electrons between the electrodes is an appreciable part of a cycle of the generated oscillations, the arrangement being such that energy is continuously supplied to the frequency determining network in proper phase to sustain oscillations.
