In a 2012 EDN article, Ransom Stephens explained how it was impossible to measure intersymbol interference (ISI) at high data rates. The reason was that ISI depends on the channel impulse ...

Signals and systems theory is a tough topic. Terms like convolution and impulse response can be hard to understand on a visceral level and most books that talk about these things emphasize math over ...

Any signal-integrity engineer will tell you that analyzing closed eye diagrams has never been easy. A transmission channel's frequency response (or lack of bandwidth) causes inter-symbol interference ...
