You are awesome Robert! I just come here to find how to calculate TOI point and didn't get anything except a lot of good information, thank you teacher.

[@leighbateman2718]

It would be great if you could do a followup explaining some real world noise figures and how they impact. (For example if you had a 16QAM system, it needs this much linearity, and therefore an IP3 of x). or compare the IP3 of some spectrum analyzer datasheets and how they limit measuring small signals near a strong interfering signal.

Holy shit your last video was before 3 years ago and i was kinda tensionised about you ... Sir i passed my digital communication because of you i dont know how many views this is gonna get but your videos are outstanding ...sir you the real MVP :)

[@WEBBERSPADE]

Rajat Gupta Thanks a lot. Other projects and other parts of life took over. but I'm now ready to get back into helping you all. so glad I can help. subscribe buddy if you haven't if that's OK?

[@rajatgupta6167]

am already subscribed sir I wish you luck for your every video hope I will meet you one day and thank you face to face too ....really sir a big thanks to you :)

Great Explanation of the fundamental concepts.

[@vijayseshan2641]

Really good. thank you. I had same question when I am going though amplifier spec. Thanks for explanation

[@lamarts1000]

Excellent job!!!!

[@ZloWieszCo]

Very nice explanation :) Thanks for that:)

[@stevenspielberg4197]

Amazing explanation

[@ahmedgaafar5369]

are you related to Mr Weber the famous Physicist that has his name of the magnetic flux unit? those 3rd harmonics are here because of the clipping of the amplifier characteristics and shaping the sine wave to look like a square wave which only contains odd harmonics...you made it sounds like the 3rd harmonics are the reason for the clipping which is rather wrong...don't you agree?...we are concerned about the 3rd one because it is just after the fundamental frequency in odd sequence 1,3,5,7,.... the 5th and up will be weaker powers and can be ignored. i don't know Rob... you have a nice track but a bit vague.

[@pentachronic]

3rd and 2nd harmonics are not due only to clipping. They are due to the nonlinearity of the amplifier (eg saturation). Clipping is typically a hard limit on a power supply.
