In my seminars I often talk about the importance of understanding at least a little electromagnetics theory, even for purely firmware people. But the subject is hard to understand and sometimes harder ...

In Example IV.2.1 we studied the Fourier series for a periodic square wave: Shown below is an animation showing the influence on the addtion of terms in the Fourier series to produce this periodic ...

We’ve seen many graphical and animated explainers for the Fourier series. We suppose it is because it is so much fun to create the little moving pictures, and, as a bonus, it really helps explain this ...

When we think of digital signals, we naturally think of logic highs and lows, signals rooted in the Fourier components of a square wave. Of course, we also know it’s not like that. At gigabit per ...
