This man explains things so easily that every student wants he makes a video about some subject. Keep the good work, the work that my teacher should be doing but you are doing it so much better, thanks.
I recommended this channel to my friends and they all thanked me! And I thank you for this! Just a mere curiosity, may i know your qualifications Sir? Because by your voice you sound so young but know so much!!
@ 5:25 if I consider my fundamental time period be T/4 to T/4 + T , I will have 2 discontinuous points instead of 3 as discussed in the video. So according to me, the total discontinuous points for 1 fundamental time period is 2 . Please correct me if I am wrong. Thanx!!
Sir, your all the lectures are at its best n very easy to understand.... thank you so much for that... I'm preparing for GATE 2018...it ll be really helpful if u upload the topics which are left like Z transform, FT...as soon as possible.... eagerly waiting for next lectures..
sir please give lectures on all the subjects of electronics and communication engineering especially vlsi design,embedded systems, and microprocessor and microcontrollers.
We say that the graph of a discontinuous function cannot be made with a single stroke of the pen. For the graphs under condition 2, all graphs can be made with a single stroke of the pen. There are no gaps or jumps where we need to lift the pen. Can you explain how they are discontinuous?

Thanks you're doing a great job for the students to make things easily realizable... but at 2:39 I'm sorry to say that's not maxima if it's considered as strict math :3 sharp edges don't make maxima or minima
actually it is...just because the derivative there is undefined, it doesn't mean it is no extremum...extrema aka minima and maxima, either have a derivative equal to zero or their derivative is not defined (case of sharp edges)...and it doesn't work the other way around...plus the definition of extremum is this: x0 ε the scope of the function so that f(x0) >= f(x) (in case of maximum) for x ε (xa, x0, xb) (or
In condition -2 example -1 , it is violating first condition by having infinite maxima ( const value) over finite range of time, still why it is considered to get F.S ?
can you help me why 4:29 the conditions below can't be expanded to fourier series or it's just can't be expanded to finite series ,but can be expanded to infinite series please help me. I have searched the Internet a lot , but can't get a precise and clear answer . :(
these videos are absolutely amazing for us but one problem is many are preparing for university exams and with limited time so it would be helpful if you could tell us in the beginning abut the level of question and wether it is imp for university pov . might save our time a little bit.
Sir Iam a great fan of yours...sir please do kindly make lectures on DSP...it's only because of you to we understand Signals and system better... please sir
very nice lecture professor! I have a question: Is the any proof of Dirichlet's condition? In some books its given Dirichlet's theorem and says that if the Dirichlet's condition are true then the fourier series converges. could you elaborate on that? I am not able to understand. I really want to know how it converges.
Please explain why Dirichlet's conditions are necessary to be satisfied for FT? what,why,how problems would appear if we take a function for FT which is not satisfied by Dirichlet's condition?
Sir, in this lecture you have said that for absolute integral the value should be finite so in in the second signal x2(t) on integrating over the given period we get the result equal to zero so why can"t we say it is absolute integral?
Sir kindly explain about discontinuity.What is meant by finite number of finite discontinuities. U said ,staircase signal having discontinuity but in that there s no gap in that right,then how can we say that as discontinuity?
Sir u said periodic seignals are those which repeat itself form - infinite to infinite but u also said that periodic signals are neve ES and if we integrate PS form - infinite to infinite so we will get ans infinite I didn't understand this
In condition number 2 u took the example of square signal, but that has maxima at infinite points o to t/2 over period t. So does that doesn't satisfy 1st condition. Could u tell
Sir What is the limit of finite term here, as in drichlet conditions which signal are not satisfying dirichlet they have also finite maxima or discontinuities.. it may be 100but finite
The last example f=tan(x) suggests half of the period ( 0 to pi/2) integrates to a positive infinite area while the other half (from pi/2 to pi) suggests a similar negative infinite area. Why is the total still considered infinite? Negative invite plus positive infinity, how is t hat defined? In this case since it is clearly symmetric, intuition is misleading me to think the integral could be zero here. That would validate tan(x) for having FS, Which is obviously wrong.Why am I wrong, what am I missing? Thanks in advance.
You are missing (Absolute). Think of it like this: You are flipping every (negative) point of the amplitude to the upper half of the graph and then you are finding the area which will be INFINITE
Is is compulsory that maxima and Minima no are same like in 1st condition we have 1 minima and 1 maxima but if we have 1minina and 2 maxima then is it FS exponential???
Why there are no lectures on 1. SAMPLING 2. Z-TRANSFORM 3. LAPLACE TRANSFORM Please upload lectures on these topics too , completing them completely ..
it has a value which is not infinity. There is a value that your function will never go beyond that no matter what you do. Example : f(x)=sinx, this f(x) is bounded to + - 1 it will never go beyond that + - 1.
in the third example tan t function converges in the interval, so it will have finite area but its doesn't have fourier expansion because its not piecewise continous(it shoots to infinity at discontinuity)
Your videos are like oxygen for engineering students :)

Same doubt I have
please upload videos on VLSI DESIGN
plz upload next video of Fourier series today...pls its my exam🙏🙏🙏🙏🙏🙏🙏🙏😫😫😫😫
Sir u said periodic seignals are those which repeat itself form - infinite to infinite but u also said that periodic signals are neve ES and if we integrate PS form - infinite to infinite so we will get ans infinite I didn't understand this
teaching with beautiful sketching. Which app Or software are used for preparing the video?
You're amazing.
Sir please upload next lectures on Fourier series
7:13 , how does this signal have infinite no. of discontinuities ? i mean it doesn't fall to zero , i'm confused
ah i got it, Thank you so much
In condition number 2 u took the example of square signal, but that has maxima at infinite points o to t/2 over period t. So does that doesn't satisfy 1st condition. Could u tell
#Wow...#Superb....#ALLAH_bless_U

Sir What is the limit of finite term here, as in drichlet conditions which signal are not satisfying dirichlet they have also finite maxima or discontinuities.. it may be 100but finite
Sir plz upload lecs of Fourier transform Z trans
Thank you so much!
sir why not are you completing Power System..

The last example f=tan(x) suggests half of the period ( 0 to pi/2) integrates to a positive infinite area while the other half (from pi/2 to pi) suggests a similar negative infinite area.

You are missing (Absolute).
Think of it like this: You are flipping every (negative) point of the amplitude to the upper half of the graph and then you are finding the area which will be INFINITE
Thanks a lot.......
sir upload the videos fast as my end sem exam is about to start
It's great sir
Sir measurements par numerical ka video banahiye na please sir
Can Fourier transform be used for periodic signal also?
Discontinuity; is given example wrong??
Condition 2: finite number of finite discontinuity .
What if discontinuity value tends to infinity, then x(t) has Fourier series or not??
observe point 3. if the signal goes to infinity then the signal wont be absolutely integrable. so no fourier series exists.
Is is compulsory that maxima and Minima no are same like in 1st condition we have 1 minima and 1 maxima but if we have 1minina and 2 maxima then is it FS exponential???
Why there are no lectures on
1. SAMPLING
2. Z-TRANSFORM
3. LAPLACE TRANSFORM
Please upload lectures on these topics too , completing them completely ..
F(x) should be bounded.( Is it not a one of the Dirichlet's conditions ?)
What is the meaning of f(x) has bounded value
it has a value which is not infinity. There is a value that your function will never go beyond that no matter what you do. Example : f(x)=sinx, this f(x) is bounded to + - 1 it will never go beyond that + - 1.
Shouldn't the Gibbs phenomenon factor in to representability?
upload videos on z,,laplace and fourier transform..plzzzzzzzzzz
Make videoes on sampling
what is discontinuity sir?
Does'nt the integration of tant in the time period will be zero? So how cant we write fourier series expansion for the same?
make Power Amplifier lecture videos please
Is is necessary for a signal to accept both 3conditions.....r else 2 conditions are enough
Sir can we find FS of x^2 in interval (0;2Π)??
Sir love you
Does fourier series convert x(t) to frequency domain?
pls upload more video
why cant we use fourier series for Nonperiodic signals?
where can I get your lecture notes. They are not on your website
sir z transform pr b lectures de do........
"signal is single valued everywhere " sir i have a confusion in this statement of dirichlet conditions. please explain.
Can u tell the time where he used the statement? I wanna check it once.
in the third example tan t function converges in the interval, so it will have finite area but its doesn't have fourier expansion because its not piecewise continous(it shoots to infinity at discontinuity)
thanks
