Figure 1 shows a variation on a sine wave oscillator, it uses just two transistors and a single variable resistor to set the frequency. Figure 1 Just a couple of components are needed for a simple ...

In electronics, negative resistance is an oddball property which occurs in a few nonlinear components. Just think that an increase in voltage across a device’s terminals results in a decrease in ...

Try an experiment. Next time you are in a room with someone, ask them to name everything in the room. Only certain kinds of people will say “air” or “light.” For most people, those are just givens, ...
