The best explanation ever... Really professional video. Lecturer doesn't appear professor-like, but give this guy just one minute, and you will see he is the best professor ever. I watched following videos as well. This saves time. In 4 minutes you learn more than reading the same thing in book for 40 minutes, or watching lesser quality video for 20 mins.
A lot of thinking and care has gone into the making of this wavelet video series, and it shows. The explanations are clear and to the point. thanks for the post @Kirti Devleker
What prerequisite knowledge do i need to understand this? I don't really know what you're talking about, but I want to know... edit: To clarify, what math concept(s) do I need to learn first? What discipline(s) of math? I've completed basic calculus so far.
This uses a lot of stuff I learned in my signals & systems course (specifically taking a real time signal and putting it in frequency domain with fourier, and function manipulation)
Sir I have a doubt . If a wavelet transform is continues means are we perform transformation on continuous time signal or if a wavelet transform is DWT is it means we are performing wavelet transform on Discrete time signals . Please clarify my doubts.
Hi, I have a question about wavelets: I want to analyse power system fault currents with wavelet. when I use 1-d wavelet toolbox, d1 to d5 coefficients are in the same time scale and I can for example find the value of each coefficient in a specific milisecond like 2.05. but when I use "wavedec and detcoef" in my mfiles, the d1 to d5 coefficients are not in the same x axis time scale. for example if my wave exported from PSCAD be a matrix of 1000 samples, d5 will be 500 samples, to d1 will be 20 samples for example. and they cannot be synced plotting together finding all coefficients in a certtain x axis like time, which is being plotted automatically in 1-d dwt toolbox. so whats wrong with my understanding or using of wavelets? thanks
Why is the equation Ψ(x/s)s=y? This seems to imply that the wavelet is made taller vertically when it is squished together horizontally. Yet your animation doesn't show this happening... Am I missing something? Why isn't it Ψ(x/s)=y?
I don't understand how wavelets circumvent the problem arising from the sine waves oscillating for infinite time and space. Aren't those wavelets composed of infinite sine waves?
Good morning sir, i wnat to pdf formate of wavelet transform and wavelet cosine transform and its application . please provide me because my exam is near.
@@riskyrisk663 thanks. I have a number of demo videos right on my channel; more on trotsenko.com.ua I currently demo it talk about it, but not disclose it yet.
Probably the best short and concise explanation of wavelets I have seen, well done

Extraordinary! Great respect (university teacher here). I have a lot to learn from your teaching tehniques!
Clear, concise, and straight-forward. Thank you.
This is a very helpful overview for every researcher working on the data analysis. Thank you for this session..
All set in less than 5 min, very well explained.
Really professional, clear and informative. Thank you !
This is how to properly teach an advanced topic. Start with the very basics. Very well done sir. Upvoted.
CLEARLY UNDERSTOOD SIR. THANK U SO MUCH
Very precise and well explained. Thank you.
Never saw such a clever way to describe wavelengths. E
Well done!
You explain the concept well clearly.
So Precise yet so clear sir. Thanks !
Concise explanation of Wavelet. Good effort.
This guy is REALLY good!
02:39 - Sorry, shouldn't the graphics of the frequency be shift between up and bottom?
The best introductory video to wavelets.! Thank you very much.
Thanks, exactly what I needed for my artificial vowel project
fun pp (-':
Thank you for your explanation

Great, simple and concise!

You explained it way better than my teacher.
Thank you very much
bless your soul
Very well explained!
Thank you very concise . Helped a lot
Ultimate & Excellent presentation on...introduction to the Wavelets..Thank you..Sir
really easy and precise explaination. thank you.
Very good explination
Great intro.. Thank you.. Can i know what tool did you use for the animation?
Nice job, thanks for this explanation!
Excelent video. congratulations

Nicely explained 👍

Great! Thank you so much.
Great sir, very nice and simple explanation
Great Explanation..Thank you....!!!
Great introduction! Thank you!
Thank you! great introduction
Can u tell me exactly wavelet filter. Video was very nice
Also why at 3:00 are we dividing by the sampling interval?
What is best between filters and wavelets for denoising
very good ..gettig interested
Hello. Very Well Donne for the Clarity and Simplicity of your lesson! (y) (y) (y)
OMG best wavelet explanation... bae .... 😍 😍 😍 😍
very good.I enjoyed
From that time -scale representation how we will obtain the frequency of our given signal??
Fantastic! :) Many thanks!
So wavelets help get the localization aspect into creating a given signal.
Thank you.
whiich will be good for emg signals either fourier r wavelet transforms
Vevvlets ! thanks mate !
I don't understand how wavelets circumvent the problem arising from the sine waves oscillating for infinite time and space. Aren't those wavelets composed of infinite sine waves?
amazing
Amazing!!!
how high are you????
Great video for post weed high!!!
Don't like your own comments.
420
Dumb question here - what does ψ mean in 2:15 ?
Stuntkoala it's just a letter wich represents the signal. like the letter f stands for function in analysis.
Good morning sir,
i wnat to pdf formate of wavelet transform and wavelet cosine transform and its application .
please provide me because my exam is near.
Please Explain contourlet wavelet Transform
Can we have a wavelet of single frequency!!??
OMG I want that swaggy MathWorks shirt sooo baaad
How to get elliot wave automated software plz suggest anyone
If the public actually cared about Wavelets, they would be outraged that there is a wavelet called the "Mexican Hat". Actually funny.
We live in a truly cucked society
how to define j for scaling?
Hey could you try this software? Encounter: 'Circuit Solver' by Phasor Systems on Google Play.
At this time their subs and view of this video are equal
几乎每句话都值得记笔记，讲的很好，可是没有人觉得他口音太太太重了吗，好多单词听了几十遍也听不懂 是我英语太差了？。。。
有字幕
Nice presentation! But the person, why so serious :/ :P
I love my dear friend
I love India
vavelets
are you an Indi?
There's something better for signal analysis.
(Disclaimer: I have invented one).
So what's the better method? Post a link or something to your work ...
@@riskyrisk663 thanks. I have a number of demo videos right on my channel; more on trotsenko.com.ua

Your explanation is too fast
complete bullshit HE IS LOOKING LIKE A ZOMBIE
