I'm working on a signal processing project about vocal system, and I'm trying to use controlling theories to solve the problem.
I need to get the transfer function, $H(s)$, of a speaker, from electrical signal to voice. But it seems that I have to use a microphone to pick up the voice. Considering the microphone itself has a transfer function $G(s)$, I will finally get $G(s)H(s)$ rather than $H(s)$.
So, is there any method to get TF $H(s)$ from electrical signal to vocal signal?
Well I have another problem. I've seen someone else estimating TF $G(s)H(s)$ by experiment. The bode diagram looks so strange and complex that I think it will be difficult to get a mathematical description of the system. So what method is usually used in controller-design when the object has a complex freq. response?
