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 ...

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 ...

At the recent InfoComm show in Las Vegas, Kaltman Creations introduced Invisible Waves, a new series of PC-based RF spectrum analyzers specifically designed for the pro audio and video industries.

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 ...

One of the most useful pieces of test gear to become generally available to the average broadcast engineer in the last 20 years or so is the spectrum analyzer. This electronic tool, while still rather ...

A spectrum analyzer, or signal analyzer, refers to laboratory equipment that is used for determining the bandwidth of an analog or digital signal. On the device, the frequency appears on the ...

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 ...

It’s the latest in instrumentation for the well-appointed shop — an acoustically coupled fast Fourier transform tachometer. Sounds expensive, but it’s really just using a smartphone spectrum analyzer ...

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 ...

For a long time, spectrum analyzers and scanning receivers have been widely used in EMI laboratories. The technical capabilities of these instruments are similar to those of a classic stepped EMI ...
