Yes, I do understand what a convolution is, I think you are the one not understanding my question. I am not asking how to calculate a convolution, obviously if I am talking about Fourier transform I know how to do this...I was wondering about the most suited way to model this physical phenomenon...

Thanks for the reply. Yes, I know rms has nothing to do with Fourier transform, I was asking if I could use it instead...

Hello, I want to do the convolution of a gaussian function and a hole. If I want to use Fourier transform which functions should I use? Can I use rms? I want to calculate the spot size of a gaussian signal after a circular aperture. Thanks!
