A basic armstrong oscillator
The Armstrong oscillator is an oscillator used to produce a sine-wave output of constant amplitude and of fairly constant frequency within the rf range. It is generally used as a local oscillator in receivers, as a source in signal generators, and as a radio-frequency oscillator in the medium- and high-frequency range. The oscillator was name after its inventor Edwin Armstrong.pt:Oscilador de Armstrong
