    I don't even know how to thank you sir. It is because of people like you that students like us who doesn't get proper educational opportunity and guidance even after going to an engineering school due to lack of resources, gets opportunity to learn. These educational videos are the soul and hear of TH-cam and what the power of internet can do to humanity. I wish with all my heart that one day a genius from anywhere in the world would watch these videos and revolutionize the field of engineering like you did with your texts and teachings. My utmost respect to you.

      can you imagine, while we are in abundance of information that is here to move us into the future, in some countries, sites like TH-cam are unavailable due to government restrictions....

    The way the courses from this Professor are lectured are fantastic. Thank you MIT and Alan Oppenheim

    So this is the author (or co-auhtor) of the legendary Digital Signal Processing textbook, published by Prentice-Hall.

    w = 3π/7 is periodic with period 14. You can actually see the first 3 and the last 3 samples on his graph are the same. To check if it's periodic, you need to see if there is an N such that w*N = k*2π for some integer k. In this case, if N=14, 3π/7*14 = 6π = 3*2π, so it is periodic.

    Thank you Sir Openhim for these briliant lectures, more thanks to MIT for providing us with such valuable resources😊

    This shows us, sometimes the less views or comments a video was given the more valuable it might be, far beyond easy to consume mainstream stuff. Really neredy :)

    Oppenheim set the path I would take in life. I had the original DSP hardcover textbook. Back then probably $20 or so. I was taking complex analysis when I took DSP in the math dept as a math theory class. How many of us in the early days of neural networks carried his book. MIT needs to do an AI enhance on the videos.

    Oppenheim lectures are like the Feynman lectures. The processing in my iPhone is based on the Oppenheim book.

      He read it correctly and later at 6:30 he said, it should'nt be less than and equal to zero.

    at approx 33:00, i don't understand why the signal is left shifted? Can someone please explain.

      capisce?

    • @rishipl3559
      @rishipl3559 5 ปีที่แล้ว

      Because h(k) is signal when h(0-k) = h(-k) so h(-k) is absolutely time shift or opposite to the h(k). Do you understood?

    if omega =rational number times pi then it is periodic, so 3/7pi is periodic

    Is the book Discrete-Time Signal Processing (third edition) the right material for these lectures? or is there other video lectures out there for that book?
