This Design Idea provides a simple, inexpensive, portable circuit as an alternative to a microcontroller to provide a wide-range source of low-distortion sine waves for audio-circuit design and ...

Single-chip transmitters proposed by some IC manufacturers have good electrical performance, but they're often plagued by some drawbacks. For instance, they're hard to find in small quantities. Also, ...

This file type includes high resolution graphics and schematics. A virtual ground is useful whenever you need to create a bipolar supply but the dc source is unipolar, as is often the case with ...

Non-contact voltage probes have been around a while and some test equipment now has them built-in. This is one of those things that you probably don’t think about much, but surely it isn’t that hard ...
