Hello,
When you convolve two signals, of lengths N and M, you need to pad the
FFTs to length (N+M-1) before multiplication.
You can take a look at my linear position-invariant filtering code at:

I understand your comments that I need zero padding when doing

Hello,
I want to calculate the root of a numpy array with negative numbers.
Here is an example:
x = linspace(-10,10,100)
h = zeros(100)
h[where(abs(x) 2)] = sqrt( abs(x) -2 )
h[where(2 = abs(x))] = 1j * sqrt( 2 - abs(x) )
Unfortunately I get the following error: Warning: invalid value
Thanks Robert,
that is exactely what I was looking for.
