Armstrong oscillator - Wikipedia
The Armstrong oscillator [1] (also known as the Meissner oscillator [2]) is an electronic oscillator circuit which uses an inductor and capacitor to generate an oscillation. The Meissner patent from 1913 describes a device for generating electrical vibrations, a radio transmitter used for …
Armstrong Oscillator Construction and Its applications - ElProCus
An Armstrong oscillator (also known as Meissner oscillator) is actually an LC feedback oscillator which uses capacitors and inductors in its feedback network. The Armstrong oscillator circuit can be built from a transistor, an operational amplifier, a …
Armstrong Oscillator - Oscillators - Basics Electronics
The Armstrong oscillator (also known as the Meissner oscillator) is used to produce a sine-wave output of constant amplitude and fairly constant frequency. The circuit is generally used as a local oscillator in receivers, as a signal source in signal generators, and as a variable frequency oscillator over the medium and high frequency ranges.
Armstrong Oscillator Circuit with Feedback Transformer
In the Armstrong oscillator design, the input is electromagnetically coupled with the output using a transformer to provide the 180 o of phase shift required for positive feedback.
