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 ...

A slick spectrum analyzer used to be the kind of thing that would have been tricky to include in a DIY project, but as [Mirko “mircemk” Pavleski] demonstrates, a modern microcontroller ...

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 ...

An AVR ATmega8 microcontroller and an operational amplifier is used to build this spectrum analyzer which can improve the audio quality of an equipment. A variety of displays are supported by the AVR ...

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.

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 ...

A new version is the result of two years of development by best experts in digital audio. RMAA raises the bar of comfort and functionality for spectrum analyzers. That's why it is a program of choice ...

Spectrum analyzers and signal analyzers are passive receivers that display the signal in the form of easily identifiable data. Spectrum analyzers and signal analyzers display raw, unprocessed signal ...

Like most modern radio communications devices, wireless local-area networks (WLANs), RFID tags, and 3G cellular systems rely on complex modulations that require specialized signal-analysis ...

Modulation Measuring the quality of the modulation is important for making sure a system is working properly and that the information is being transmitted correctly. Understanding the spectral content ...

Back in the 1960s, when I started working in radio broadcast engineering, an oscilloscope was my “eye” on what was happening with equipment. That tool served me well and is still in daily use in my ...
