Matlab Examples: Fourier Series of a Square Wave

[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) ^^

Are you actually a Doctor??

[drjctu]

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

[pnnorton]

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

[demolatio]

thanx

[djstud1987]

very informative...

[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.

This is a recorded video using the zoom capabilities of Camtasia from Techsmith. Hope this helps! Dr J

1. I get a buzz every time I press the "play" button, why

2. I get the same graph as you do, but when I try to do the zoom, it doesn't look like yours. How can I make it look the same way?

congratulations for your video!

from where we can download matlab software anyone can tell me plz?

[michaelfraguada]

Dude the legal way is to purchase a student license. But IDK if that's what you are looking for. The student version isn't bad and not too expensive although as a college student myself money is always an issue. Good Luck

[drjctu]

Matlab does not have a function as far as I know. The purpose of this exercise is to check the calculation of the fourier coefficients were performed correctly. When I have time, I plan to put a video together for other functions: pulse, triangle, sawtooth, etc.

[andyvalencia]

Fuckin awsome! But does matlab have a function, that can tell me, what amplitudes and frequencies I need for "ANY"!given function!!!!??????? not just the simple square wave. Thanx!

thanks for watching and the advice...I'm started waling right for the last 3 weeks since it's starting to warm up at the high colorado mountains. John

great video. ure breathing kinda hard though, hit the gym!
