Thank you very much for sharing.

[@lunagirlmg]

very nice, i watched it with 0.5 speed, i liked the animation

[@abdalfettahasharaa389]

What an amazing idea

[@sheetalverma2426]

I did hear anything. It is with audio or not.

[@teslamars2259]

Excellent

[@radioinestable9355]

Genial. Buena explicación!

[@fmbroadcast]

Amazing !!!

[@onlooker774]

Good example on how a probable good work is ruined by incorrect presentation, dislike for too quick move, you can't read and follow the explanation at that speed...

What a wonderful explanation! I still have a question. Why Z is 50 Ohm at 3:13 ? Where is the other 25 Ohm that you write Z = 2* 25? Also, Why Zp finally sees 50 Ohm? it should see 25 Ohm (thanks to Line with 90 deg, 35.3 Ohm) and the other branch that is 50 Ohm 90 deg. How does it become 50 Ohm in the end?

Because of current! In the combining point, the impedance looking into the right side (output term) is a constant value: 25 Ohms, but two branches' impedance will change according to the current value. The more detailed explanation you can find in some books. Good luck!
