On 16:19 should alpha and beta be applied to both the x's and the y(-1)?

[0mikage0]

In 13:41 shouldn't the definition of the accumulator be y(n) = sum of x(l) where l is from negative infinity to n only, not positive infinity?

Thank you NPTEL for putting up this channel and the DSP series of lectures. A huge token of appreciation to Dr. Roy too for his uncanny ability to teach the most difficult concepts in a relative ease that only he can offer. I have horrible teaching faculty and that really worsens the subject for the students but measures like this youtube channel have really helped students like me, big time.

[Eorzean]

LOL. lots of them are confused with linear time invariance. poor dr. roy, his greatness is wasted by his students. you're wonderful dr. roy. thank you for sharing your pedagogy with us.
