Matlab Examples: Fourier Series of a Square Wave

Reference: http://FreedomUniversity.tv

This simple demo shows how a square wave can be represented as other functions such as a sine wave using matlab. This video also serves as a Matlab and/or simulink tutorial as applied to the concept of the Fourier seriesI will post a more thorough discussion on the Fourier Transform.

Are you actually a Doctor??

[drjctu]

Not a medical doctor but just a Professor with a Ph.D. Dr J

[Baraggal]

Can't I buikd a simulink model to compute the fourier series coefficients of a periodic square wave?

Thanx

[drjctu]

The model will be more complicated involving multipliers and integrators if you use the mathematical definition of finding Fourier. coefficients. This example is just a demo showing that a periodic function consist of a whole bunch of sinusoids and may be use verify the Fourier calculation and signal bandwidth.

same question like Barragal...I cant find any Fourier-Block for simulink...

thanks

[drjctu]

There is no fourier block in Simulink or at least I'm not aware of. You can use the Spectrum Analyzer found in the Signal Processing Toolbox.

@drjctu you are a messed up doctor

[savinibarreto]

my grandma can do that

[irfaanfr1]

Thanks a lot!!!!

[getson84]

nice Idea but for this simple task you can use a calculator. A tip for you, use the shortcuts to copy things (strg + mouse) or (strg+c, v) ^^

Sorry I knew that. I didn't quite ask the right question. What I was interested in was what is your Ph.D in?
