Hi,
I've a discrete transfer function (z-transfer function), how can i get equivalent transfer function in s-domain or its frequency response like an analog system?
The transfer function is:
a
H(z)= ---------------- where a,b,c are constants
1+bz^(-1)+cz^(-2)
I need to check what is its behaviour, 'cause i don't know it
