When first learning about and building electronic circuits, the first things all of us come across are passive components such as resistors, capacitors, and inductors. These have easily-understandable ...

Engineers generally focus most attention on active components such as transistors, optoelectronic devices, ICs, and the like. In any design, however, the characteristics of passive devices ...

Back in the Jurassic days of electronics, before Lee de Forest developed the three-element “grid audion” (a triode vacuum tube providing amplification) around 1906, circuits and channels were passive ...
