DEFINITION

Classification: 331/167

(under the class definition) Oscillators of the active element type wherein the frequency of oscillation is determined by an inductance-capacitance circuit of the lumped element type and which oscillators are not provided for in any of the preceding subclasses.

SEE OR SEARCH THIS CLASS, SUBCLASS:

95, for oscillators utilizing butterfly resonators.

96, for oscillators utilizing distributed parameter resonators.

128, for gas tube means to shock-excite an LC circuit.

154+, for oscillators utilizing electromechanical resonators. 165+, for systems wherein the resonator is shock-excited.
