Sometimes it is necessary to split a single power supply in two or more parts which are not necessarily equal. This is the case with 6-, 12-, 15-, 24-, 36- or 48-V power supplies from dry batteries or ...

This file type includes high resolution graphics and schematics. The spread of h FE values in a batch of transistors may be wide enough to cause unreliable performance during mass production of a ...

Last month we showed you how to use resistors to reduce voltage. While it's a viable solution for many cases it isn't for others. As noted before, resistors work for devices whose load remains ...

From the point of view of the power supply the audio amplifiers are generally of two types. The first type is used mainly in applications with a single power supply. Some can be used with a dual power ...
