Many of today's digital oscilloscopes include fast-Fourier-transform (FFT) capability for frequency-domain analysis. This feature is especially valuable for oscilloscope users who have limited or no ...

FFT-EM is an innovative method that represents a combination of FFT and EM techniques such as scanning electron microscopy (SEM). The technique is often used to determine the interior and surface ...

What causes the degradation of aluminum electrolytic capacitors in power-supply designs? What is ripple current and how can it influence capacitors in power-conversion circuits? Step-by-step ...

In earlier articles, we looked at the basics of fast-Fourier transforms (FFTs) and how to set up an FFT on a modern digital oscilloscope. In this post, we’ll take a brief look at what that modern ...
