I was reading this article about resonators.
Quote:
The sine wave that matches that particular frequency will get amplified by the resonator, and all of the other frequencies will be ignored.
As far as I know, in picture below, the capacitor and inductor below makes up an oscillator circuit which oscillates at some frequency so that it can be matched and amplified by resonator.
So what is this resonator that the article is talking about?
