DEFINITION
Classification: 331/165
(under the class definition) Systems wherein means is provided for applying an electrical impulse to a resonant circuit which circuit is then permitted to oscillate freely at its natural frequency.
(1) Note. Systems utilizing an active element and a feed-back circuit to sustain forced oscillations are not considered shock-excited systems for classification herein, but will be found elsewhere in this class, e.g., miscellaneous L-C oscillators of the active element type are classified in subclasses 167+.
SEE OR SEARCH THIS CLASS, SUBCLASS:
79+, for beam tube oscillators wherein a sweeping, or modulated or bunched beam of charged particles may shock excite a resonator.
128, for systems wherein a gaseous space discharge device is utilized to shock-excite a resonant circuit.
