Fourier Analysis: Fourier Transform Exam Question Example

Fourier Transform example if you have any questions please feel free to ask :) thanks for watching hope it helped you guys :D

[@AndrewJJ-0114]

I never knew that Björk knew so much about Fourier Transforms.

[@raghulsankar1153]

lol

[@_SeaH0rse]

Bjork, very good one😄

[@patrickningi4259]

prof: you shall start your exam in 8 minutes me:

[@studyaddicts2772]

So u studied all other topics🥺🥺

[@g00dvibes47]

Awesome explanation. I’ve taken up to differential equations but always in the real numbers, but having used the Fourier transform once or twice in a computer and other kinds of transformers like the Hadamard which stays in the real numbers but is related to the Fourier, I can say that learning an introduction to complex integration from you has been easy, thank you!

[@99law99]

Thank you for your kind words! best of luck :D

[@dvscrobe]

This was a good problem to watch. Made me realize I needed to refresh on Euler's formula to convert the complex number back to the sine wave function.

[@antonionoriega155]

Great job explaining this example! Exactly what I was looking for. :)

[@tayhuiling3831]

first thought in my mind when i enter this page and the video played automatically was OMG bEautiful voice..

[@sidsifou999]

Hi give me you facbook baby i love you

[@DanielGonzalez-sw1kf]

Also and for being more concrete, you could say that 6/w * sin2w is equal to 12*(sin(2w)/2w), which is equal to 12 sinc(2w), which is the Cardinal Sinus function. I say it because maybe if it's a signal processing exercise you should end your exercise saying this. Btw good video! :)

[@99law99]

thanks Danieloglez! appreciate your input. :)

[@joshuabenjaminbillano8917]

Wish there we're more vids just like this on fourier transform :)))) this is such a great video

[@danielm3569]

Excellent video, easy for the layman to understand.

[@BismillahNasir]

came here to refresh my memories on Fourier transform... thanks a lot... calming voice by the way.

[@fatmagamal3701]

omg thank you very much , you explain better than my prof.

[@yunusemreuzmez8308]

It is very good example to how to find Fourier Transform of any function.Thank you.

[@adityav7526]

Can you do more problems on Fourier series?..I found this really helpful..

[@dotsedossou9573]

you have done very well. the video was good and you were very simple with good explanations. congrats!

[@talsokolinsky6611]

I didn't understand the last thing, you said that sin(x) = 1/2j * (e^(j)-e^(-j) but then when you input the value to the formula you haven't add the half, so you got 1/2j instead of 1/4j? Or is it just my misunderstanding?

[@alessandrofb7968]

Simplest explanation I've seen so far. Thanks a lot :)

[@martyguild]

how come the fourier transform is the integral from -infinity to infinity, but you evaluate the integral from -2 to 2? i assume it is because the function is defined as 0 outside of these BOUNDS (they are not limits, but bounds)... therefore the area under these parts of the curve will be 0, but this is not something that should just be hand-waved away. you also drew a theta and called it delta...

[@notebook2866]

........................................This is the BEST video in the whole universe............................................

[@gooddeedsleadto7499]

Step by step So kind of u Thank u Please in a similar way do few KZbins on FFT.

[@Earthquake91]

i wont need this in my whole life but I am still listening to you. thumbs up for your voice. damn I fell in love with it.

[@adnanmohamad2883]

OMG , u saved me 😭 thank you so much , thank god i watched your video 🙏😭

[@99law99]

Most welcome, happy it helped!

[@imogenbooth6061]

You have a very pleasant voice - its as nice as your explanantion. Many thanks for the video!

[@altaherbushraadam7085]

Dear teacher ,good job and nice explanation. ,##really I enjoyed I need more from these examples specifically

[@MA-qz1sd]

the Fourier transform of a rectangle function which is what your piecewise function is here is the sinc function, not the sine function, which is what you have as the result, can you clarify this, please? Thank you

[@edmondscott7444]

Very well explained.

[@mahmoudroshdy2809]

A very beautiful video that has a simple way to explain, so I was hoping that you would explain something about fast Fourier transform.

[@mathqube]

Good problem chosen which explains concept of fourier as well as numerical solving

[@Arpitsaxenaaaaaaaa]

I m a big fan of ur teaching mam thanx a lot mam :)

[@demurch0]

Just what I needed for my signals and transforms exam. Thanks very much :D

[@vojtechsejkora1554]

How the solution will change if the interval where f(x) = 3 was between -2

[@muhammadyazeedtaseeu8539]

What a nice video ! with a nice Voice ....... I really enjoyed this video simple to understand

[@the_samology]

Your voice is so Sonorus and sweet.. 😊😊

[@sreeparnadas2929]

Very well explained in a simple manner.. this was very helpful... thank you so much!! ^_^ And yes, your voice is very sweet! :) Looking forward to more such videos! :)

[@99law99]

thank you :) best of luck in your studies ! :D

[@mohsenentezary4640]

it was effective, I hope you continue with more examples

[@Moe5705]

Thank you for the video. I like your clear step by step approach.

[@boshboshish]

when we reached to the result stage (3/jw)[e^(2jw)-e^(-2jw)],,,can not we say that the answer can be (6/jw)[sinh(2jw)] instead?

[@AjayKumar-ps4ro]

ur voice is too sweet .. and tnks a lot fr the video . and we r having our exams frm day aftr tmrw.. so it may help a lot..

[@bedouinarab251]

can i ask you a question ? if they ask us to find FT of f(x)={1+x/8 where -8

[@armyon8385]

It really helped me. & the year is 2021 : ) Thank you!!!!!!!

[@travelnimarktv2406]

Does Time domain and Frequency Domain were both the same? same solutions and formulas?

[@kakikader327]

What it someone in 2023 loves your voice

[@akramiraqi]

Hello, how are you? I hope you explain the cases of the Six Fourier Transform.. an excellent explanation

[@saronna_7]

please, can u explane more about this subject and more example. and explane about properties of fourier transform

[@car2020able]

I am student at university .. it really useful here also .. thanks so much

[@tashilhamo-qd9ot]

Why did u used Fourier transform pair equation?

[@federicopagano6590]

I love to check the limit case in the answer that's a nice 12 ✔ (when w=0 and applying L'hôpital's rule) 12.sinc(2w)

[@zacharyippolito9000]

SO EASY TO FOLLOW THANK YOU!!!!

[@jacobvandijk6525]

The beauty of things lie in it's simplicity. Thanks, LW.

[@fayssalelansari8584]

why didn't you add 2pi to the fourier equation? exp(-j2piwt)

[@bensonmwirigi6772]

Shouldn't there be a 1/√2π on the transform formula?

[@ndumisontuli6659]

can you help with this one please. write the complex fourier transform of F(x)= 2sin(x) - cos(10x).

[@ahmedel-masry7717]

thank you for explaining this question .. your explain is very simple :)

[@eeee2097]

easiest "exam problem" i've come across

[@omarhidalgo6719]

Hi, I'm glad to found this video, very useful and specific, thank you. I have a exam in 3 weeks, maybe you have a book that you could recomend me about Fourier Transform difficult exercises to practice? thanks again.

[@moof1232]

did you pass?

[@aryantendulkar142]

keep posting more videos while keep in mind revised the video before uploading because in this video you pronounced wrongly for theta and f(x) instead f(t). so just encouraging you to keep it up. Thanks for basic explanation of FT!

[@ElectroMentor]

i think its omega not w

[@lima1944]

True. It's a ω (omega), not a "w", usually used to signify frequency in radians/sec. She also calls theta (θ) "delta".

[@blessingshenjere484]

thanks it was actual easy to understand.

[@PGN354]

How did you get the 2w to replace the bracket

[@niets421]

Thanks a lot. Your explanation is simple enough

[@danishopo551]

your voice is so sweet in love with that for learning you need loving voice as well

[@tarifalmodares4679]

You are great!! Why did you stop making videos??

[@manofvision1]

Why did you multiple by 2/2?

[@niom2262]

Exelent!..but,why not you make vedio of signal &system.? Carry on & try to continue to upload some extraordinary vedio about signal& system.. Best wishes for you

[@altaherbushraadam7085]

Which depart you study for

[@pradeepattri8375]

thank you for this video it was really helpful, can you please find the sine and cosine transform of e^-bx and evaluate for integral 0 to infinity, (cosax/a2+b2) da

[@rajivnarayan5214]

Gotta remember that rectangles Fourier transform into a sinc function. You could've also turned the equation into unit step functions as well. U(t+2) - U(t-2) and integrated those using the formula table. But this was a good video

[@JAln-ge5vf]

Finally a Fourier Transform question on KZbin, THANK YOU! btw lol is that Pringles?

[@antacilgell]

thanks a lot , I will do midterm exam in tomorrow you help my life lol .
