When working around mains voltages, it can be useful to know whether a given circuit is live or not. While this can be done by direct connection with a multimeter, non-contact methods are available ...

One of the coolest things any sound system can have is some kind of musical visualization. Thumping level meters that pump with the volume are a great example, and were particularly popular in the ...

With the trend toward miniaturization, temperature effects in power electronics are more pronounced than ever. If you’re dealing with temperature fluctuations in your circuit, you may need a ...

A converter that tapers off a 4 mA input to zero, and adds the input and the tapered off 4mA signal to create a 2-wire 4-20 mA output loop.

Most switching power-supply controllers provide non-latching fault protection. Satisfying a requirement for a latchoff response to a fault often requires the addition of excessive and redundant ...

Researchers developed a compact, low-noise bandgap reference using a single resistor, improving stability and efficiency for sensitive biomedical electronic devices.

The original Circuit groovebox developed something of a cult following thanks in large part to Novation’s relentless updates. So it was no surprise that the company decided to give it a proper sequel ...
