[El Artis] just finished building an audio spectrum analyzer that uses a character LCD. The uses an Arduino to drive the display, but unlike other meters that use the microcontroller for analysis, [El ...

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.

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 ...

Measuring phase noise with a spectrum analyzer. The primary advantage of dedicated phase-noise analyzers. The cross-correlation method. Using a spectrum analyzer is the oldest, most straightforward, ...

No instrument, whether in the time or frequency domains, is suitable for all use cases. Signal/spectrum analyzers shine for ensuring standards conformity. Oscilloscopes tend to be more versatile, ...

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 ...
