Hi,

 

 

I will present to you my first personal initiated project named Spectrum analyzer.

This spectrum is based on sampling signal and calculating his spectrum using FFT algorithm.

Attached here presentation, documentation (french), electrical scheme of amplification circuit and source code of both programs (Computer and PXS20)

 

Picture of the spectrum analyzer with TWR-PXS20, TWR-SER and TWR-PROTO :

And here we have the spectrum :

Thank you, and i hope you like it
