While [Vinod] says he’s not an expert in this sort of thing, we really like his audio spectrum analyzer build from a simple microcontroller and LCD display. It is a well-studied fact that every audio ...

It’s the end of the semester for [Bruce Land]’s microcontroller design class at Cornell, and the projects coming off the workbench this semester look as awesome as any before. For their final project, ...

The circuit has been designed to create a spectrum analyzer that will provide an analysis of a sound to determine at various frequencies, the volume of sounds that make up the overall sound spectrum.

This audio spectrum analyzer utilizes an ARM7 LPC2138 microcontroller to create an FFT algorithm while performing digital signal processing without the use of special DSP processor. This audio ...

Juergen Grau data the new DIY audio spectrum analyser called the Magilyzer EM800 complete with EM800 Magic Eye tubes, which has this week launched via Kickstarter and is now available to back with ...

Electronics enthusiast and developer Juergen Grau has returned to Kickstarter for 7th time to launch his new Nixie tube audio spectrum analyzer. Watch the demonstration video below to learn more about ...

EE’s electronic test instrument coverage achieved critical mass in the mid-1980s, including a spectrum analyzer story in the August 1986 issue and subsequent August issues into the 1990s and beyond.

The analysis of RF and microwave signals in the frequency domain used to be the forte of the spectrum analyzer, but now it’s become a choice between signal analyzers and digital oscilloscopes. How did ...
