I've covered several different programs that are useful when doing electrical engineering in the past. In this article, I want to look at a program called linsmith that helps you do calculations or ...

You have probably heard the statement about standing wave ratio: “I changed the length of the transmission line and reduced the SWR.” Or the opposite statement, “I changed the length of the ...

An article (called “How does a Smith chart work?“) that I wrote for our July 2001 edition has come back to haunt me, as several readers this week have called it to my attention. These readers' ...

The Smith chart is a staple for analyzing complex impedance. [W2AEW] notes that a lot of inexpensive test gear like the MFJ-259B gives you complex readings, but fails to provide the sign of the ...

[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 ...
