AT&T Archives: Similiarities of Wave Behavior - Energy loss by impedance mismatching

Not sure if this is the correct forum (mods please move as needed)

Dr. J.N. Shive of Bell Labs demonstrates and discusses the following aspects of wave behavior:

Reflection of waves from free and clamped ends
Superposition
Standing waves and resonance
Energy loss by impedance mismatching
Reduction of energy loss by quarter-wave and tapered-section transformers

Well worth your time to watch, it is 28 minutes but it goes quickly.

I came across it through another website discussing power transmission lines (http://hackaday.com/2017/05/03/model-of-a-transmission-line/)

Good stuff for radio folks, too.

dots and dashes make my head hurt.

I think, in text, dah dit is easier on the brain.

Dah dah dah dah dit it, dit dit dit dah dha, dah dit it, dit, dah dit dah, (this separates the men from the computers) dah dah did did did it dah dah dit.

People can make it out, computers can't. Running MHZ together is like a song, and most people catch it first time, what little I have done with it. Computers never can figure it out unless I space the letters.
