Deconvolution problem

Started by October 30, 2008
Hi all, i have a problem with the deconvolution of a signal with an impulse response. I have a signal that is similar to my impulse response only shifted forward. The output of the deconv function results to be a sort of impulse near at the end of the vector. The correct result i think should be an impulse shifted forward with respect the beginning of the array. What could be the reason?
