one of the best explanations i have seen so far. thanks

I realy enjoy from watching your video i was like you i saw 50 video and content in internet but now i found what is modulations.👌

I made your subscription 1000 from 999

🙏🙏🌹🌹

Thanks

Wonderful and crystal clear teaching ❤️

niceeeeeeeeeeer

The best explanation on the planet

Awesome teaching ❤️

Brilliant explanation!

Thank you for the great explanation :)

beautiful explanation

Hi nice vid. Btw you sound a bit like female version of Andrew Mallett (The Urban Penguin) !

Awesome

Thank you for sharing this knowledge.

Thank you 😚😚😙

wonderful video thank you

This is simple and amazing. Modulation explained at it's best!

Holy shit this is good. Thank you so much

Excellent explanation, I appreciate that. Clear voice, clear explanation, and understandable. Well done!

very well explained ... I really appreciate Thanks!!!

Great video. I am trying to figure out the waveforms. Would a 01 be created with a sine wave that has traveled 45 degrees at the beginning of the symbol period, a 11 be created by a sine wave that has traveled 135 degrees at the beginning of the beginning of the symbol period, a 10 by a sine wave that has traveled 225 degrees at the beginning of the symbol period, and a 00 being created by a sine wave that has traveled 315 degrees at the beginning of the symbol period?

Amazing, thank you!

Good lecture to start with

Does this happen before or after a 4 way handshake?

Thank you so mucccccccc, you are f amazing goddess!!! if you just knew how many videos I have been watching to understand this and finally you just simplified and being able to explain to someone who is new and is not engineer , yet at least , thank youuuuuuuu

Very clearly explained modulations, particularly for QAM.

I have a homework question. Can you support this topic?

Very clear explanation, thank you very much

Nice video. Well explained. Thank you!

very nicely explained. thank you very much!

great video, thanks a lot!

My 15 colleagues couldn't explain me how it exactly works. Thank you very much. Now i can explain it for them.

Thank you for that video, it is very helpful

1.5h university course in only 10 minute, top!

hey thanks for the info , what about the PCF ??

Jeeeesus, this is a brilliant video for beginners.

I have come across a different explanation of QAM where 2 waves are used (one sine wave and one Cosine wave - the Q comes from these being Pi/2 out of phase) and the points on the grid are the amplitudes of the 2 waves. I think there is BPSK where the amplitude changes from positive to negative).My question is, are there 2 versions of QAM - one using one wave and another using 2 waves?

Damn wow this is a really clear explanation. I wish it was the first video i found. Thanks it really helped!

I think g doesn't support 64 QAM. But awesome presentation

Beautiful!!! Great explanation

Thank you. A very clear explanation.

This is a great video, thank you so much!

very nice video

Yours is the best explanation i found in UA-cam.. Which reference material did you use

must of new devices have many internal anttena so there is 2 to 3 signal handling in the same time and also the fade signal is handling

Best explanation ever heard on this topic.thanks a lot. Wish I could get whole topics taken by you.

Angel thank u for coming my way, you are indeed a TutorAngel. this breakdown is so revealing. thanks for imparting

Merci.
