FFT and Deconvolution

ROOT
1

I am trying to convolve two square functions using root as a simple test for more complicated cases. To do this I have two arrays of numbers which describe each of the fucnctions, and can be convolved using the standard formula. Does anyone know how to do this using FFTs? Given that the product of the FFTs of two waveforms G and H is equivalent to their convolution, there must be a way of using TVirtualFFT to do this.

No problems, I solved this issue.

Thanks.

Could you please post your solution?

Can you imagine how frustrating it would be for a future person in your position facing your problem? They find someone who had already faced the problem but didn’t post their solution. Think of it as saving your own time.

Thanks.
