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 ...

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 ...

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 ...

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.

[Camilo] built a spectrum analyzer to use with his audio system (translate). The hardware is quite simple, using an op-amp, microcontroller and LCD display. He chose an LMV324M low-voltage op-amp ...

In the not-so-distant past, contractors and consultants who wanted to check parameters at a number of FM stations had to lug around a frequency-agile FM monitor and related gear. Today, DSP technology ...

Juergen Grau has taken to Kickstarter once again to launch and raise funds for his new analogue audio spectrum analyser which takes the form of the Magilyzer Mk II, which builds upon previous designs ...

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 ...
