Before I go to the exam, I just want to say THANK YOU SO MUCH FOR THIS VIDEO! You have saved my whole semester of this crazy hard material!! Surely, I'll watch your DTFT and DTFS videos for my next semester! 👌

[@techjunkiejdb5476]

Rhesa MR thank you

[@mubashiryaseen42]

I couldn't learn it in the whole semester 😄, best explanation 👌 And yeah if you don't mind i just wanna share my personal habit that we Muslims keep silence 🔕 at the time ⌚ of Aazan. Thank you so much for this wonderful lecture ☺️ God bless you and your family forever.

Sir you have put 2π in the term of T in stead of 1.I think it should be 1 as time period is given as 1. Thank you sir

[@techjunkiejdb5476]

Yes . I got it wrong . Thanks for correcting

[@SAISRIVIDYA66]

Sir. In the place of T u put 2pie in stead of 1 in last problem. Excluding that it's awesome.. I think plz Check the last one. Tq sir

[@techjunkiejdb5476]

Cherukumudi Saisrividhya yes 2pi must be replaced by 1. Thank you.

Welcome 🤗

[@ARVINDKUMAR-nb2yv]

its one of the best video

[@geethamadhuri8023]

Well explained sir, last one can be further simplified as you told previously in a problem e^(jk2π) is always 1, so I think after simplifying we get j/(k2π). Thank you for uploading.

[@techjunkiejdb5476]

yes we can :)

Problem 3 at 20:29， why is it a minus tan for the phrase of x(k)?

[@techjunkiejdb5476]

Because we are calculating the phase . It's calculated as the addition of phases of numerator minus addition of phase of denominator . Since in this particular case the phase of numerator is zero , the answer would be negative .

[@gandrakavya8201]

Awesome Sir tq very much

[@karolenjadallah7774]

thanks for many much

[@techjunkiejdb5476]

Welcome

[@srinathv7097]

in the last sum you have substituted omega instead of T in the analysis formula?

[@techjunkiejdb5476]

SRINATH V that's a mistake. I should have substituted value of 'T' .

[@prashanthag3308]

Super sir good explanation and we need some more examples

[@techjunkiejdb5476]

Ill definitely try to solve some more :)

[@nakkaabhishek4621]

thanks a lot. This video helped me a lot.

[@sreenathak6355]

Sir in this what ever the coefficient of t you had taken it as w but in dtfs you had compared the coefficient of t with 2pi/N why are we doing that in dtfs please explain tomorrow I am having my exams

[@techjunkiejdb5476]

Dtfs equation is different than CTFS ! In DTFS we usually expand the trigonometric functions into exponential functions and group them together and compare it with the original equation ! If discrete values are given then directly put in the DTFS eqn .

[@rekhar9599]

very well explained sir!!

[@sonaliyadav3506]

Thank you so much sir

[@techjunkiejdb5476]

All the best !!

[@ranjithaphutane8269]

well explained tq sir

[@JamilKhan-hk1wl]

answer for final question is -1/jk2pi, you can simplify the exponential and you shouldve divided it with T not 2pi

[@techjunkiejdb5476]

Jamil Khan it was a mistake 😕

[@loppol4995]

Awsome video,finally understood the concept.thanks

[@chethanshrinivas6505]

sir your teaching is very good ,but in last problem instead of writing 1 you wrote 2pie.over all good

[@techjunkiejdb5476]

chethan s yes that has to be changed.

[@jasonjimbun2686]

Example number 5 suppose to be 1/T where T=1, but why are you put 1/2pi instead? 2pi are the value of Omega(w).

[@techjunkiejdb5476]

Yes . Its a mistake. It has to be 1. Thank you :)

[@jasonjimbun2686]

Thanks for the Reply bro :)

[@AKASH-rv6fk]

In 31:57 differentiation must be done only "T"

[@techjunkiejdb5476]

Yes I have differentiated with respect to “t” . Only 👍

thx bro

nyc one sir

[@srinathv7097]

very nice lecture

[@manojgangadharan9045]

How we can find the equation of square wave of period T?

[@techjunkiejdb5476]

It's 1 from 0 to T/2 and -1 from T/2 to T . If the amplitude is 1 and -1 .

[@vikramchaudhary8693]

in problem 5 if T=1 why is putting the 2pi

[@techjunkiejdb5476]

vikkky singh it's wrong. It has to be 1. 😊

[@ranchezbuster2740]

29:20 T is 1 not 2pi

[@techjunkiejdb5476]

Right that’s an error ! Thanks

This is continious time . Must not graphics be as a line? Why did we find the point again? This is not discrete time.
