Phase

How the Fourier Transform Works, Lecture 3 | Phase

Sine waves have three properties, amplitude, frequency, and phase. In the last lecture, we dealt with amplitude and frequency. In this lecture, we explore the third and final property of a sine wave: Phase.

This is the fifth in this series of videos which take a new and visual look at the maths behind the magic of how the Fourier Transform works.

Thanks for watching the video How the Fourier Transform Works, Lecture 3 | Phase

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 YouTube channels. Thanks n highly appreciated for given viewers a educational programmes.

Finding this is Channel is the most important discovery I made in 2020

[James_Hello]

Totally Amazing. Mark should have his own TV show

[johncruz]

I wish you were my teacher when I was going for my electrical engineer degree many moons ago!... MANY KUDOS

[Lexyvil]

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.

[gergerger]

Man, I'm so happy I found your channel. Top quality stuff!

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

Hey! Great work Mr Mark. Is really sad you not getting the attention your work deserves.

[jiripingpong]

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.

[panduwilantara]

Now i understand everything about fourier because of you, thanks a lot newman

[manoj_thori]

This is the man I was looking for.. thanks sir

[AlphaGeminorum]

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!

[thryce]

really like these thanks. the negative frequency explanation was very good

[curtpiazza]

Great! Love the illustrations of the Pathagorean Th. Love the illustration of the tangent function! Thanx!

[Swimmingshiraz]

These are great! I've been avidly waiting for the next one. And here it is!

[tanzimahmed]

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💝💝

[sixstation]

Great demo showing Pythagorean theorem with liquid. 1 to 2 and back to 1 dimension

[akashr]

Thankyou sir, to give me an insight
in DSP and Maths

[landonoffmars]

That's a nice lecture on phase. Thanks.

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?
