1. A person who oscillates or vacillates in action or thought; a waverer.
2. Something that moves to and fro; a system or device that oscillates.
3. An apparatus for generating oscillatory electric currents, or for generating electromagnetic waves by means of such currents. Also, a device for generating sound waves.

An oscillator whose frequency is determined by the value of a voltage, current, or power.

An oscillaory is a mechanical or electronic device that produces a back-and-forth periodic motion.

A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air resistance or friction.

In electronic oscillators, electrons oscillate with a constant period and also require the addition of energy to replace energy loss.

Electronic oscillators are used to generate alternating current and high-frequency currents for carrier waves in radio broadcasting.

1. A device that generates alternating current.

It is characterized by a circuitry that feeds a portion of the generated energy back into the system to sustain its operation, and by an electron stream that is coupled between the screen and the plate to reduce the effects of the load.

2. An oscillator employing a multigrid tube in which the cathode and two grids operate as a conventional oscillator and the electron couples the plate-circuit load to the oscillator.

The anode-circuit load is coupled to the oscillator through the electron stream.

An oscillator in which the operating frequency is modified by changing an electrode voltage or current.

A crystal oscillator circuit whose oscillator output frequency can be varied or swept over a range of frequencies by varying a DC modulating voltage.

1. An oscillator whose frequency of oscillation can be varied by changing an applied voltage.
2. An oscillator having an output frequency that varies with the applied direct current control voltage.
3. An electronic oscillator designed to be controlled in oscillation frequency by a voltage input.
3. An oscillator having an output frequency that varies with the applied direct current control voltage.
