Certain types of discrete transistors, the NPN 2N2222 and the PNP 2N2907, can be operated as inverted mode switches where “inverted” means that the collector is made to serve as an emitter and the ...

The transistor is probably the most important invention in electronic engineering and the basis for nearly all integrated circuits (ICs). The transistor is a three-terminal electronic device that can ...

2N2222 devices used, but practically any junkbox NPN will do Electromagnetic fields are everywhere, all around us. Some are generated naturally, but in vast majority of cases, it’s we humans that are ...

PartSim is used in this example to simulate the Common Emitter Amplifier. The base bias voltage is set with the voltage divider arrangement. The input signal is amplified by the 2N2222 NPN transistor.

In last week's installment, we showed how to get started with Csound. This week we take it to the next step by constructing a homemade MIDI controller circuit and use the new device to control Csound ...
