Lecture 1 - Digital Signal Processing Introduction

[@danivdouro]

God bless this man, I passed my DSP subject thanks to this man, i am studying at the hardest telecom engineering University of my country and he is better than all my teachers, it was a pleasure following his lectures, he is the best DSP teacher in the world. Listen every word of him. Pay attention please

Can you please suggest the best nptel lecture for signals and systems? There are too many in KZbin. Which of those professor's lecture is the best?

[@TheGajanan11]

simply amazing. even if a student doesn't know much about signals and systems , he can still figure out dsp with this video. i hope we have teachers like this , life will be much easier and science more enjoyable . thanks a lot SIR

[@Businessbayindia]

IIT'S are always great with a clear and creative lectures

[@Chandankumar-zs2tb]

the way professor teaches is amazing

[@pogi09282805724]

good thing this kind of videos are available here in youtube!!

[@TheHaytt]

Gratitude from Pakistan , thank up you so much Sir , its quite certain will never have chance to meet you but prayers and respect always stays at top for you

[@ravindratseeker1926]

Stood topper in university in DSP just because of all your video lectures... thanx a lot sir, Thank you very much.. Your teaching style is an extraordinary... Thank you once again...

[@saurabhsingh4903]

Good , party

[@SynaesthesiaOfficial]

I have a solid computer systems background. but I didnt know a thing or two about DSP 1 month ago, now im programming my filters. This has helped me a lot. I feel more confident with complex math also. Im checking MIT courses too. thx

[@angelofweb]

Excellent introduction. Especially the reference to discrete time signal as analog and then the intro on coherer and spark gaps...they really lead up to present day. I also like the emphasis placed on different types of signal processing methods.

22:25 it was bose invention of galana cat whiskers ( Natural simiconductor diode ) for first generation radio and he did published the paper without claming any patent but later markoni patented with demonstration and we think it was markoni who invented wireless and Tesla did also contributed because of his Tesla coils , spark gaps and his wireless Power transmission dream .

I have one objection: Economies are digital and not continuous signals since transactions are instant and not gradual. Therefore we have a 'step' on someone's wealth when they make a transaction. Great introduction nonetheless.

[@JyotikaPandey277]

as far as I have studies..according to that... they have never used negative integers in equation. so may be.. by integer he meant positive integer... but the result (graph) can be shift (not sure) so.it can be both positive and negative integer.

Hi to all , can some one answer my questions What does the spike in the autocorrelation represent? Does the spike hold all the information about the signal?How can we use the autocorrelation to help us detect the signal?

[@piyaltaru]

A very nice video. I have just one suggestion. Please use ppt slides (with animations, if need be) for display. That will give this video international standard.

[@dittocopy]

The one thing I am confused about is when he says that time is discretized in terms of integers, the integers can be negative or positive. But time can never be negative in practical terms so why would there be negative time in the signal processing ??

You should think that the positives represent the future and the negatives the past being the point "time = 0" your reference.

+Deepjyoti Das Understand the difference between analog and digital .. and ... continuous and discrete ... see oppenheim wilsky first chapter (or maybe second) ... they have given right explanation with example waveforms .. The discrete and continuous nature is related to axis of independent variable ... and analog and digital is related to dependent variable ...
