This circuit generates a dual-tone bells ringing similar to most door-bell units. It can be used in many applications other than door-bell. In the Notes below several options will be given in order to ...

For example, often lawnmowers have two switches in series with each other so that both switches need to be pressed before the mower will turn on. The power ring circuit is also a parallel circuit. In ...

Abstract: An electric circuit representation of a side-coupled single-mode microwave ring resonator is presented. The ring resonator is coupled to the feed lines along a quarter-wavelength of its side ...
