10 Facts About Electronic oscillator
2.
Negative-resistance Electronic oscillator model is not limited to one-port devices like diodes; feedback Electronic oscillator circuits with two-port amplifying devices such as transistors and tubes have negative resistance.

3.
Nonlinear or relaxation Electronic oscillator produces a non-sinusoidal output, such as a square, sawtooth or triangle wave.
| FactSnippet No. 538,098 |
4.
An Electronic oscillator can be designed so that the oscillation frequency can be varied over some range by an input voltage or current.

5.
An Electronic oscillator was built by Elihu Thomson in 1892 by placing an LC tuned circuit in parallel with an electric arc and included a magnetic blowout.

6.
The arc Electronic oscillator was rediscovered and popularized by William Duddell in 1900.

7.
Electronic oscillator attached an LC circuit to the electrodes of an arc lamp, and the negative resistance of the arc excited oscillation in the tuned circuit.

8.
Vacuum-tube feedback Electronic oscillator was invented around 1912, when it was discovered that feedback in the recently invented audion vacuum tube could produce oscillations.

9.
Electronic oscillator showed that the stability of the oscillations in actual oscillators was due to the nonlinearity of the amplifying device.

10.
Electronic oscillator originated the term "relaxation oscillation" and was first to distinguish between linear and relaxation oscillators.
