(x^2)-0.5
Just that this is not bandlimited.
Thanks!
Is it :
sum : (1/(n*n))*sin(twopi*n) where n:1,3,5,7,9
Bandlimited parabola waveform using FFT ?

Anybody knows the summation formula for a bandlimited parabola waveform ?

Take a look at the Music DSP Source Code Archive. There is a concrete example published by Joe Wright (including pdf documentation) for doing exactly that.tranceinstitute wrote:Anybody knows the summation formula for a bandlimited parabola waveform ?

...erm... this is not exactly FFT (Fast Fourier Transform) - not even inverse FFT, but a kinda specialized Fourier series synthesis...

It's
sume(1-n) : cos (n*2*PI)* 1/(n*n)
sume(1-n) : cos (n*2*PI)* 1/(n*n)
