Fourier Transform for the Ti Nspire CX CAS?!

Unread postby ahmad nour el deen » 09 May 2015, 20:58

Is there any program that's written for the TI nspire to calculate the C.T Fourier Transform?
Something that is similar to the laplace transform..
for ex; if I enter: delta(t), I get >> 2 pi delta (w)
and so on...

I only found one but for the TI 92/89... Is there anyway to port it to the nspire?
Thanks

Thanks, but that's not the Fourier Transform.. it's Fourier Series :(
one of them is the D.T.F.T ... But I need the Cont. Time F.T

Oh, right, didn't see that.
Well then, I'm not sure right now if there are any programs already done, but can't you calculate the integral directly ? It might just work with a (CX) CAS Nspire.

Basically just

The integration almost can't be done easily although it's CX CAS.. it returns the integral as it is unfortunately!
I looked for something that can be used to port the TI 89 program to our Nspire, but I only could see the code using notepad++ with some characters being written in a wrong way.

do you or anyone know where I can get this file?
also about z transform.
this website goes down
I look at whole the internet and couldn't find Fourier Transform
thank you
