What a great exposition of the theory of modulation as well as the history of its use for one of its most widely used applications!

This professor kinda sounds like Heath Ledger's Joker lol

A great tutor with awesome explanations. Thanks for the lecture

DAMN!May the gods bless him

1. "It takes lots of power if the antenna is significantly smaller than the wavelength of interest." 04:00 2. He wants to construct a lambda antenna, but what about spatial sampling theorem? 07:30 3. X(omega - omega_c) 13:20 3. "Frequency Division Multiplexing: Frequencies have to be high compared to the message frequency." 25:00 4. Modulation and aliasing? 25:45

thank you for the lecture .

great lecture, thanks!

loved his instruction very social

thanks for the lecture

Really enjoyed this! Thank you!

Modulation (Part 2) is missing from the playlist, but is available on the mit website.

Superb explanation, prof. Scientific findings with historical background. A great way to engage the class.

Great lecture! Thank you.

What a great lecture indeed!

How to see conjugate symmetry? 15:45 Multiplying cosine with a function so the product becomes 1 is a bad idea, as with the zeros the function would have to go to infinity. 22:30 Synchronous modulation. 22:50 (You have to be exactly synchronized in phase?) Red and blue Dirac? 26:45

Thank YOU I used to watch the 1975 course, It was pretty good but ofc we need something new :) Thanks MIT because U changed the world

Thank you

Excellent lecture from a brilliant sprite ❤

thanks for awesome lecture!

What are your expecting to get from MIT OpenCourseWare, if not videos like this? Or is the problem the volume?

watch NPTEL (IIT Delhi)analog communication lectures by Prof Surendra Prasad.he is absolute gold.

very nice lecture.

I like that they use the metric system :)

Actually, the antenna length should be lamda/4 or lambda/2.

One thing I hate todays college education, not just this source, but throughout US high education is that the courses can't cover the full content they intended to, mostly because of lack of time. Like this lesson is all great right till the end, when the professor rushes through some good content. It is like right after you build up all the fundamentals, then you lose the product. I often hear professors complain that they have to shrink a two semester course into one, missing a lot of good stuff. The students suffer this way.

nice lacture

Pardon my ignorance, but doesn't e^(-jwt) = cos(wt)-jsin(wt)? instead of cos+isin?

Good

Professor Frink!!

👌

and then, sidebands appear out of nowhere, by choosing the correct formula, none of these professors actually know, in a technical way, how those sidebands appear in a technical sense. it is called amplitude modulation because when originally thought up the composite showed an amplitude modulation and the changing of the plate voltage of the tube, no one suspected the presence of sidebands until over a decade later. And here we are teaching with composite waveforms to perpetuate the misnaming. It is like the direction of electron current flow, professors just keep teaching what is passed along even if it is wrong, because they can not unlearn what they initially learned. So, do you, after watching this, know where the sidebands came from without resorting to parroting the formulas above....I did not think so.

how do you choose R and C value in the circuit?

Tesla was the inventor of radio.

I will be leaving now

His modulation is hot hahah

when a teacher asks the class questions over and over again and no one can answer it, means you suck at teaching the material

He's kind of smug.

I don't think the lecturer is in touch with his students... Brilliant person, not a great teacher

The course materials is very much IT technology and the explanation of, And it spams my understanding in the objective analysis due the information containing IT technology in the mere example of a module. Much rather have a business module explanation which gets into the different types of business within a control list in enumerated way,which presents meta data or styles of a business which might determine the provisions in ramifications to create an off sets that has been procured.

Thank you
