Your videos have made this subject easy for me. Great effort sir. Thanks a lot.

[ozzyfromspace]

I’d be so screwed without the internet 😂😂 Thank you, those integrals really clarified a lot of things about the convergence of Fourier Series

[somashekar-hogw]

Hi Sir, Thanks for your wonderful effort to support students :-)

[peichunchen]

The best math teaching video I've never Many many thanks!!

In one of the previous videos U told that we can't find F.T of u(t) directly as integral of e^(-jwt) from 0 to infinity leads to e^(-jw(∞)) = cos (∞) - j sin (∞) term which is undefined . But here, U took e^(-(a+jw)(∞)) term as zero directly. Why is it so? Did u assume e^(-a(∞)) = 0 multiplied with undefined term [ which is e^(-jw(∞)) ] as zero?
How can (0)(undefined term) be zero as it is undefined?
Thanks for your awesome lectures :)

Thanks Sir for this wonderful work.

...love 4rm Nigeria 🇳🇬

[Abu-kxei]

Thank you very much for the instructional video, really helpful for my grad school.

In 3rd time how did you write mod of t as negative from negative infinite to zero?

[Helinsalih-rmiw]

i have midterm tomorrow in engineering analysis and this save thank

[jyotiprakashbaishya]

I don't usually comment, but the quality of videos produced by this channel is better than my college. 6months of semester classes wrapped in such short and crisp videos.

[adarshkumargupta]

sir, while substituting the upper limit after integration a complex number (a + iw) when multiplied to infinity has been written to be equal to infinity.
Is that true??

[phanindrareddy]

Awesome videos with wonderful explanations

[exodus]

Sir you are doing a great job sir. Keep the good work going . Would you let me know what % of syllabus is left for signals nd systems. ? Thanks for all your lectures. Without you I would be nowhere . Thanku so much

[darshanraoghatge]

Can we get a PDF of solved problems of FT?

[estilomaniaco]

how do you know that u(t) is 0 from -infinity to 0 and 1 from 0 to infinity?

[aanchaljain]

Are exponential function always absolutely integrable ?

[chetanteli_iitbombay]

Sir please compare this lecture to first lecture of FT in which e^jw....w=infinity not define you said and in this you putiing i. sin(jw)+cos(jw)....w=

[mohemahmoude]

Sir you are doing a great job sir.
i have a question in 05:07 what if we write (jw-a)*(-t) instead of (a-jw)*t the result will chang or not

[Vhrb]

In 2nd a case what if a<jw while applying (-) ♾️

[c.cody.]

Professor how do we know this exponential signal is absolutely integrable? It should have infinite area thus not absolutely integrable so we cannot use the equation
