Mr Mark Newman is a great teacher n mathematician. I am fortunate to turn to his channel accidentally n will not regret whole heartedly. His methods of explaination on the subjects is awesomes n brilliant. I will definitely recommend others to watch his TH-cam channels. Thanks n highly appreciated for given viewers a educational programmes.
You've earned yourself a new subscriber. I stumbled on your more recent videos, and then found my way into this Fourier Series series. It's exactly what I needed as an electronics student working with waveforms.
Your videos provide excellent intuitive explanation of the concepts, visually showing what the formulas actually mean. The quality of the visuals and animations is impressive.
My introduction to and study of ontological maths led me here and I'm ASTOUNDED at how awesome your explanations are, Mark. And to discover that you're a musician, too (and have chosen some very nice end vid electronic music) tops this entire thing off. Long live the Fourier Transform!
I'm flattered. This is my therapy for not having a clue and feeling so stupid in my signals and systems classes all those years ago. If only I had known then what I know now. If I can help students avoid the frustration I went through then that would be a job well done.
Great teaching skills of engineering maths. I've long forgotten all the maths I learnt back in the late 70s and early 80s, but I remember how difficult it was to get my head around Fourier Transforms, among other things. Eventually the penny dropped so that I could do enough to get through exams, but I don't think I ever really understood it. Could this by my opportunity to finally understand it, some 40 years later?
It's never too late to learn 😊. If I have helped broaden your understanding of the Fourier Transform then that will make me very happy and give me the satisfaction of a job well done.
once Mark finishes the FT series would be gr8 if he gave this level of detail on "What is a Fourier Series? (Explained by drawing circles) - Smarter Every Day 205" that video just jumped over the details ... looking forward to cranking out some code to implement that process yet am still in research mode on just what is going on
If your interested in coding some of Fourier's Theories, take a look at my Blog on-which these lectures are based. There is a whole section on the FFT which ends up with an implementation of the code in Javascript. See: www.themobilestudio.net/the-fourier-transform-part-9
You are not getting it wrong, it's a mistake in the video. 660Hz means one "cycle"`== (1/660). seconds And so: a 30 degre phaseshift("delay") takes (1/660)/(360/30) Seconds == 0,0015151515.../12 ==[( 1*30)/(660*360)] == 1/(660*12) == 0,000126126... Seconds best regards

This series (no pun intended) is truly incredible. I really do appreciate someone making this work of genius come alive with pictures and nice explanations. You are a true scientist and a great orator!!! Thanks so much
Wow. Thank you so much for your kind words. I absolutely LOVE making these videos on so many levels. Also, I have my own demons to exorcise about the way Maths is taught. I didn't understand the Fourier Transform for years and always felt a bit stupid that I was incapable of understanding such a basic tool of signal analysis. Then I began to work with it in my professional life. Necessity became the mother of invention and so I HAD to understand it. What you are watching is basically my own journey through the concepts of the FT from complete dunce to that wonderful eureka moment when the penny finally drops. I want to help others on that journey of discovery and enable them to get to that eureka moment too. Hence the videos. Please share them with whosoever you think could benefit from them. Do you know any LinkedIn or Facebook groups where people are looking for this type of approach to the FT?
An intermediate guitar player trying to learn how circle of fifths can be helpful to create music introduced me to you. And a curious electronics engineer motivated me to have a look at the video suggestions on the RHS "How Fourier Transfrom works". I must mention, you have become a role model for me. What an amazing work. Though I donot use Fourier transform in my daily engineering stuff which involves developing/assisting in some digital circuits, and majorly developing firmware for the microcontrollers to add required functionality to the products, but your videos made me to remember all that i studied during my university days. I really wish I had a teacher like you.... You are awesome, and I am sure your videos will help me in future.. It is a request, please keep up the good work. Thanks
With phase "cancellations", when there is a sin(x) and sin(x+π), I had always thought that the amplitude of the combined waves would be 0? I understand that the amplitude would be positive for both. With the Pythagorean theorem the values would be positive and would not cancel out. Am I misunderstanding a fundamental piece here?
This video is part of a series on the Fourier Transform. The playlist for the series can be found at th-cam.com/play/PLWMUMyAolbNuWse5uM3HBwkrJEVsWOLd6.html. I've released up to Lecture #4 at the moment. Lecture #5 is due in 2 weeks time and Lecture #6 a fortnight after that. (I'm in final stage editing on Lecture #6 at the moment). This series on the Fourier Transform has taken me 4 years to produce and I'm still not finished. It's taken me so long as can only work on it in my spare time. I'm looking into funding options at the moment so that I can devote more time to producing them.
Thank you very much sir for this amazing work. Explanations and visualizations are on another level. Now I know exactly what I'm studying, you made this confusing stuff super interesting. Take love. Wish you good luck💝💝
That depends on where you start from. Although the convention is to start from a cosine wave and treat its phase as zero, in this example, I started with a sine wave. Everything is relative, as Einstein would say. So if we start with a sine wave, we have to shift its phase by minus 90 degrees to produce a cosine wave.
@@MarkNewmanEducation Well, sure for engineering it does not matter. But if you then make a video on Fourier series or transform, you can end up showing that the transform a sine is indeed 90 (for the positive frequency) and not zero. And so that could cause confusion. But great videos btw.

Thanks. Glad you're here!
That's a nice lecture on phase. Thanks.
You are welcome! Glad you liked it.
Now i understand everything about fourier because of you, thanks a lot newman
These are great! I've been avidly waiting for the next one. And here it is!
Thanks. Glad you like them! Lecture #4 is also available and lecture #5 should be out in 2 weeks time.
I wish you were my teacher when I was going for my electrical engineer degree many moons ago!... MANY KUDOS

There are not any good videos on Fourier transforms until now. Wish I saw this two years ago.
The 3 blue 1 brown video is also good! Albeit a bit confusing if you don't take some time to think about it
@@NN-sp9tu just watched it after reading your comment. Thanks for the suggestion. It really was a good video.

Pls make video on log functions also
Thank you for amazing explanations .
You are welcome!
Sir, thank you, you really helped me.
Glad to have helped.
Where am I calculating wrong? the video at 5:04 shows that the phase shift is 0,00126s, and I keep getting 0,000126s
You are not getting it wrong, it's a mistake in the video.
660Hz means one "cycle"`== (1/660). seconds
And so: a 30 degre phaseshift("delay") takes (1/660)/(360/30) Seconds ==
0,0015151515.../12 ==[( 1*30)/(660*360)] == 1/(660*12) == 0,000126126... Seconds

Yess i m going through all of them
Thankyou sir , to give me an insight
in DSP and Maths
How do you define phase?
Mindblowing.
pipi popo poooo
Thank you very much sir for this amazing work. Explanations and visualizations are on another level. Now I know exactly what I'm studying, you made this confusing stuff super interesting. Take love. Wish you good luck💝💝
Great! Love the illustrations of the Pathagorean Th. Love the illustration of the tangent function! Thanx!
Is this in your books? If so I will buy them right now
I use a similar analogy in the books. My whole stratergy is built on trying to demonstrate the concepts visually wherever possible.
Great demo showing Pythagorean theorem with liquid. 1 to 2 and back to 1 dimension
Excellent video! Thank you. 😄
At 3 minutes the phase is minus ninety, not zero. For a cosine it would be zero.
That depends on where you start from. Although the convention is to start from a cosine wave and treat its phase as zero, in this example, I started with a sine wave. Everything is relative, as Einstein would say. So if we start with a sine wave, we have to shift its phase by minus 90 degrees to produce a cosine wave.

My mind is completely blown by _why_ opposite/adjacent creates the tangent. Height goes up, angle goes up. Length goes up, angle goes down. Just... wow. 🤯
