On the page about impedance transformation, the last figure showing what the source sees for the 4th harmonic (full wave) the subtext says "Source sees 56.25 Ω reflected from 100 Ω load at end of full-wavelength line (same as half-wavelength)." But this should be 100 Ω. The graphic is correct, just not the subtext.

I take this as a valid correction. Could I have a second opinion?

 

The full wavelength should be the same as the half-wavelength.

This looks like a copy and paste error where the editor didn't correct the figure.

It source "sees" 100 ohms ... at both half and full wavelengths.

 

Thanks all, for finding the error which I managed to introduce some years ago when adding captions to images.

Source sees 100 <OMEGA> reflected from 100 <OMEGA> load at end of quarter wavelength line.
