These days, streaming services are a great way to listen to music or podcasts on your computer or on the go. However, they lack one feature of the MP3 players and streamers of old: visualizations!

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 ...

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.

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 ...

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 ...

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 ...

Radio seems to be an unofficial theme for The Hackaday Prize, with a few wireless frameworks for microcontrollers and software defined radios making their way into the quarterfinal selection.
