The post looks at a Colpitts oscillator. You can usually tell a Colpitts oscillator by remembering it starts with C and the feedback loop has a split capacitor (as opposed to a tapped inductor).

We’ve read a lot about oscillators, but crystal oscillators seem to be a bit of a mystery. Hobby-level books tend to say, build a circuit like this and then mess with it until it oscillates.

Here's why he prefers the oscillator: "But the Oscillator was something that Karen Cramer said to me, that what you have to do is you have to find some gauge that measures whether people are too ...

The Duffing oscillator, or Duffing equation ... differential equation with or without forcing,” the scientists explained. A forcing function is a function that appears in the equations and ...
