An indispensible tool for solving transmission line and waveguide problems, the Smith chart was invented in 1939 by Phillip H. Smith as a graph-based method of simplifying the complex math (that is, ...

[Ralph] is excited about impedance matching, and why not? It is important to match the source and load impedance to get the most power out of a circuit. He’s got a whole series of videos about it. The ...

Even in these days, when news travels instantly and there are few secrets, it’s possible to miss an important or interesting story. That’s what happened to me recently: I was doing some online ...

Impedance matching is one of the perpetual confusions for new electronics students, and for good reason: the idea that increasing the impedance of a circuit can lead to more power transmission is ...
