I remember when in 1983, as a graduate student in UMass, I spent so many hours watching the Betamax versions of these lectures at the library. Great lectures!
Great Video, it is nice to see how after more than forty years, it is still applicable to our time. A time where where teaching prowess superseded ego and theatrical skills. Great job, Dr. Oppenheim!
they did have microphones in 1975. in fact many of the microphones used today were around in 1975. the sm58 is used today by most performers and is from the 1960's. The idea that all modern technology is superior is (of course) nonsense.

probably oppenheim processed these signals himself
This camera is so 'awesome' when compared to 1975 standards. Why didn't you record Walter Lewin's lectures with the same camera? His 1999 classes are so...low quality :/
7:00 - Maybe it's just me, but where the reel-to-reel recording is played back to show the unenhanced/enhanced recording, I can't hear a difference at all. Anybody else feel the same way?
Listening with ear plugs, there is definitely a difference. I perceive it as the first being muffled, the other more open, crisper, but also more noticeable noise. Edit: at 9:40 ish they removed the noise as well.
@jsm666 True. But, it's painful even for the seventies. Brings back bad high school memories. ;) Anyway, I love the attire and instrumentation - " ...displayed on a computer ray tube ..." Thank goodness the mathematics is just as relevant today as ever. Everything else (sin intro music) are an awesome, awesome bonus.
Audio better than my profs online lecture on zoom
i think it's safe to assume that MIT used professional equipment for this and your prof used a $20 webcam.
definitely correct
They know digital signal processing. They processed the video and audio signals then uploaded
Oppenheim has been my favourite author on signal processing. Its great to view his lectures on net... thanks MIT...
sinusoidal mustache, eye-catching tie and great charisma. Dr. Oppenheim is the best
raised-cosine filter
I remember when in 1983, as a graduate student in UMass, I spent so many hours watching the Betamax versions of these lectures at the library. Great lectures!
I don't know if I've ever seen a more 70s looking man.
I feel like I'm being abducted by aliens at the beginning
that was funny :)
Dude, I was thinking exactly that.
Holy phuck😂
Thumbs up if you think his mustache is the sinc function
Yeah
Yes and the best thing i am replying you in 2020
I read your comment at the start and now I can not unsee it in the whole lecture.
wow he really has good articulation, this is actually interesting, amazing 1975
Great Video, it is nice to see how after more than forty years, it is still applicable to our time. A time where where teaching prowess superseded ego and theatrical skills. Great job, Dr. Oppenheim!
The ever best Introduction on Digital Signal Processing!!!!
Thanks to that Intro I'll never sleep again :(
We owe him a lot.
thanks for providing best videos MIT is the best.
Thank you so much for such a neat and simple to understand video. My former DSP teacher should watch this video!!!
He is, hands down, THE BEST PROF IN THE SIGNAL PROCESSING UNIVERSE.
I looked at his Signals and Systems lectures as well.

The sound quality is pretty impressive, considering it was 1975.
+quicktech They recorded it in MIT. That says something ))

@ lmao
or maybe they used DSP on a DSP lecture audio.
I love the computer music intro- you can hear it trace through the over-tone series!
Thank you for sharing such a high quality course. Knowledge should be open to everyone.
He was born in 1937. The intro sounds like he was into modular synthesis.
Alan V. Oppenheim is the God of DSP! I wish I had found this earlier...
He *literally* wrote the book on it
Ah, a (wo)man of culture as well
Thanks for these videos. Alan V. Oppenheim's book is one of the best DSP books ever.
I cannot thank MIT enough for providing these valuable lectures. Thank you so much.
I will watch this entire series today
I like how this was just mostly theory in the 70s without any real systems doing this yet now today it underpins everything we use.
I'm definitely going to find it useful and interesting... It's Oppenheim Himself!
wow thank you very much, i am studying Signals and System by Alans Oppenheim book and here he is! :D
we still doing it 9 years later
il mitico Oppenheim del libro di elaborazione numerica dei segnali!!!
you've been fight with time and didn't get old...
these are still golden!
The opening intro is the sound of your GPA dropping the moment you decided you wanted to do DSP.
In fact this was pretty advanced technology for those years
1975 - that was the year of the freak snowstorm in June that stopped a cricket match at Buxton in Derbyshire.
Thank you MIT. I found a DSP Book from Mr Oppenheim in our Library/
14:20 .. wow can't believe HDR effect was cutting edge technology back in 1975 where as now its called shitty instagram effect.
Excellent articulation! And he really loves Vesti la giubba lol🤣
It's 2012 and still being the base!!! from discrete time signal proccesing courses around the world XD all our reference to study are here =)
This camera is so 'awesome' when compared to 1975 standards. Why didn't you record Walter Lewin's lectures with the same camera? His 1999 classes are so...low quality :/
In 1975 they had just discovered colour and had to saturate everything to the maximum lol
Muito bom! Genial.
Shame that even today's college courses can't match the course which was recorded back in 1975!
wow what an introduction... 😍 just wow💛🧡
Same name, same idea today. Pretty cool.
So we had digital images before digital music?
Ron Burgundy?
OMG, HE is Prof. Alan V. Oppenheim
, the one wrote the $200+ textbook.
The one and only

@@roygalaasen, vielleicht doch zu einem HNO-Arzt gehen, um dein Gehör überprüfen zu lassen. Der Unterschied ist sehr deutlich!
will there be any update for the 1975 version?

Kids... 9:05 is called 'Fast Forward"

im from sri lanka 🇱🇰
thank u this valuable course
Or a sinc stache?
@lowmax64 i don't think it's annoying; it's trippy.
Omg it’s 1975 😱
yes i too agree the music at the beginning is soooo annoying!
@TreacleMary You're being too nice.
Hello sir, I am a 2023 student
thank you for your Lecture sir I got PhD in BITS Pilani by listening to your lecture sir
That's impressive
the birth of acapella
Nice tie.
@SuperGZK It's very seventies.
Is there a never version of this course?
Why would you want a newer version?
This proff is da best.
Says 1975 right in the title
SUM(hair, mustache, uber-tie, shirt, jacket) = 1975
praise to the internet
I'm starting out to self-learn DSP, is this resource outdated now ?
@jsm666 True. But, it's painful even for the seventies. Brings back bad high school memories. ;) Anyway, I love the attire and instrumentation - " ...displayed on a computer ray tube ..."

Is this video still relatable.?
Yes
Tell something about DSC: Digital Signal Controller
the intro music really started bugging me out...
Who else is here in August 2019 ??
Me hu lavde yha kya kar rha hai
I'm here in 1975
I think they use his textbook at the university of washington
7:00 that man needs an ipod
Must be crazy to witness such amount of progress in your area of expertise, the guy is still alive so he probably had an iPod at some point in time
Hi it's Professor from the tv series Friends :D
Wow, thanks for this information :D
Ron Burgundy!
@zxc210188
mmm it is not at the same sequence as you read his books .
This opening song scares me...
Vim pelo Coach de Fracassos.
Not too sure about that intro music...
The intro music is painfully annoying.
1975 😱
15:16 :)
bro speaks like a textbook 💀
dat mustache...
dat tie...
dat MP3 player XD
This lecture is kinda old, am I right??
10 years older by now!
dat hair...
lold
