In an earlier article, we discussed the basics of setting up a fast-Fourier transform (FFT) on an oscilloscope, and why you’d want to use an FFT to get a frequency-domain view of a time-domain signal ...
An interactive signal processing challenge exploring FFT, spectrograms, and filters. Decode signals, design filters, and uncover hidden audio mysteries. Dive into the fascinating world of signal ...

Abstract: Some digital sampling oscilloscopes (DSOs) can perform frequency analysis using an on-board FFT (Fast-Fourier Transform) calculation applied to a time-based acquisition, which provides ...
