(under the class definition) Subject matter wherein means are provided for effecting a change in oscillator circuit connections or for adding or substituting circuit element thereto so that the system resulting from such change or substitution is substantially different from the original oscillator circuit.
(1) Note. Typical systems classifiable herein are oscillators convertible to (1) amplifiers, (2) detectors, (3) wave meters, (4) triggered multivibrator, or oscillators convertible to another type of oscillator, for example, (5) sine wave generator to square wave generator, (6) Colpitts oscillator to Hartley oscillator, (7) Colpitts oscillator to
tuned feedback oscillator, and (8) fixed frequency crystal oscillator to tunable LC oscillator.
SEE OR SEARCH THIS CLASS, SUBCLASS:
58, for oscillator systems wherein the system simultaneously performs some function in addition to generating oscillations (e.g., amplifies an external signal or detects an external signal).
161, for crystal oscillators wherein means are provided for substituting one crystal for another in the oscillator circuit.
179, for oscillators in general wherein the frequency of oscillation is adjustable in discrete steps, e.g., by switching in or substituting inductors and/or capacitors having different fixed values of reactance. SEE OR SEARCH CLASS
330, Amplifiers,
1, 82, 93, 101, 104, and 112 for subject matter including amplifiers convertible to oscillators.
