This engineer could have just stuck with the Gateway 2000-branded, Altec Lansing-designed powered speaker set. But where’s ...

An audio amplifier was once a fairly simple analogue device, but in recent decades a typical home entertainment amplifier will have expanded to include many digital functions. When these break ...

It used to be a rite of passage to be able to do the math necessary to design various bipolar transistor amplifier ...

If you've never heard of a 'DAC' before, you might be surprised to hear that you most likely use one everyday. DAC stands for digital-to-analogue converter and any device that delivers digital sound – ...

In the 2023 National Electrical Code a permissive rule introduced a new branch circuit rating of 10 amperes. This has raised some questions about what size conductor would be required and where the 10 ...

Abstract: With the fast development of advanced communication systems, wideband low-noise amplifiers (LNAs) have become more and more critical as they determine the overall performance of the ...

Abstract: Edge audio devices can reduce data bandwidth requirements by pre-processing input speech on the device before transmission to the cloud. As edge devices are required to ensure always-on ...

Make your analog breadboard experiments instantly audible with Elektor’s first analog T-board, featuring a compact class-D amplifier, DC/DC converter, and built-in speaker. Simply plug in the Audio ...

This paper presents a clear and fast design procedure for directly matched low noise active integrated microstrip antenna front end circuits. Initially, a theoretical analysis is given for the overall ...
