Hello everybody, I'll try to explain my situation the best I can... I'm sampling a signal that comes from a device (u(t)) through RC circle (h(t)) to A/D (y(t)) after that I'm saving it to a file.
The RC circle is a black box for me, so I want to find it's impulse response by sending an impulse signal instade of the device signal and record it by A/D.
my questions are:
1. how to send a real impulse to the LTI system? (I've learned that impulse should be infite amplitude for very short moment)
2. ets say that I have this impulse response as a vector of data, how by how can I use this vector to create an inverted function to reconstruct u(t) by using H(s)^-1.
I hope that I was clear enough, I would be happy to explain what is left in the dark
Thanks, Uriya
