[SciPy-User] scipy IFFT question ( time N+1 wraps back to time 0 )

Hi,
I've got the transfer function of an LTI system (H(s)). The input to the
system is a 1 ns pulse delayed by X ns ( x(t) ) If I compute the response
function by taking the fft of the input to the system multiplying and then
taking the ifft I see the impulse response to the system just shifted by X
ns. That's expected but the problem is that the tail of the system
response wraps around and appears at time 0 in the ifft. NOT what I
wanted. How do I get rid of this?
Thank you,
Matt
