Insanely good explanation. You can just see he's the one who wrote the book that my teachers are trying to explain...
Yeah!!
And dont succced to teach correctly
,😆😆😆😆😆😆
A brilliantly lovely lecture. As Daniel Colegrove commented, it is apparent that he is the one who wrote the book.
He proceeds with what is introduced in the book so cleanly and masterfully, and it's with this confidence that he provides such a concise lecture. Illustrating the adding up of components vividly brings what would be so ephemeral into life, and thus ignites joy in the student.
His lectures are the only thing saving me from failing the signals and systems course. Thank you so much.
I spend all my leisure time writing algebraic derivations, thank you.
These lectures are priceless.
i think there is an extra minus sign in the bottom part in 22:03
Inside the integral, it should be e^(j(k-n)), not e^(-j(k-n))
+Henry Hung Yes you are correct.
It was corrected in the book.
Thank you for quality explanation and insight on a Fourier series.
Sir looks so smart and charming
Wow man you are just amazing, my college is teaching this subject from the book written by you.
what he said at the end was gold
so much better to learn here than in class... my professor is kind of confusing
I think my professor doesn't know what he is talking about.
Hahah I feel you, same here.
no man. it is because its hard to follow in class and take notes. on youtube at home you can focus more, pause the video, rewind, use multiple sources that makes something understandable whereas w/o multiple sources (like in class) youre like huh?your prof is probably fine. in a technical class, thats how it is. you go to class to find out what you need to know then you go home and learn it. this isnt social science
Wow his words are like bombs.crystal clear concept.
the bomb drops, and boom, you are intelligent.
This is a difficult topic, very academic. The textbook and these lectures read like a math theory class. I can say that the students at my university struggle greatly with this material.
Wow. The explanation is so clear.
what a fantastic lecture. thank you to all who are providing this .
Thank you based Oppenheim
That's an amazing lecture.
No . Thank you sir . your lecture was awesome !!
That's why people like him make history !
Why it's zero when k is not equal to n
That creepy intro music.. :D
I like it
sounds a bit star trek-ish to me
WOW! A big doubt has cleared.
great lecture
Watch it in 1.25x speed otherwise it is very irritating
+Eren Demirel Let's agree with 1.5x. +fraunos 2x is too fast for a person whose mother language is not English, I think.
Lol I bet you don't understand shit watching 2x.
yeah 1.25x is fast enough to basically cut of his pauses and slow parts but not too fast because the material is still difficult to comprehend.
I've been using 2x speed =p he's indeed very slow.
nice video, explains a lot more than my teacher did in lecture. But i kinda find it hard to accept that a frequency can be positive I mean 2pi/T > 0 because T>0 right? if anyone can answer i owould be so glad
Visual Intelligence w is positive but k is not so kw may be positive or negative,it depends on value of k.You can say that negative and positive gives direction of rotation.
I don't understand the relations at 18:00. It seems that all the imaginary terms are missing in the summations. For example, shouldn't we have + Ak * j * sinkw0t in the first one?
If the signal x(t) is real, then the imaginary terms are all cancelled out.
Cool lectures....
nice mustache Alan sir, nd great lectures :)
What is the chapter nmbr and topic nmbr in book of this lecture?
:) Owe you sir :)
how very retro
nice lecture ,can i get the soft copy of his book free? i badly need it,plz help
Are there any other lectures better these for signals and systems?
Did he explain Parseval Theorem in this course ??
Nope
ok
7:33
nice course but that's not 2011 it's probabily 50's or something though :P not me music tells
+Semih kılıç response of MIT OCW to a similar question in comments Lecture 2 video:
"The video was recorded in 1975 but published on MIT OpenCourseWare in the spring of 2011. In some ways though, these materials are considered timeless. Even though the material is old, it is still current and considered good reference material."
i don't understand why he says the integral of the complex exponential over T {T for m=0 and 0 for m not equal to 0}
Just convert exponential into cosine and sine and try to integrate it you will get the answer.
How can he come up with those equations in 8:44, I remember that response is different from lecture 4, which should be h(t-tao).
applying the convolution commutative property x*h = h*x, the equation from lecture 4 is equal to the one here.
@@yougoog1Thank you!
demek sadece türkiyede sinyal dersi yokmuş :((
+ishak ektiren Türkiyede de var canım....sen hangi üniversitede misin?
+Gara Dayibb mersin
mezun oldun mu kanka :)
