[Simon Inns] just rolled out his latest project, a PIC based spectrum analyzer. He’s using a Fast Fourier Transform routine crafted in C to run as efficiently as possible on the 8-bit chip. The video ...

[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 ...

Swept, vector, and real-time are a few of the terms being used to describe today’s signal analyzers. They help to identify major changes in spectrum and signal analyzer capabilities that have occurred ...

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 ...
