Consider a discrete transfer function that represents an anti causal filter such as a derivative filter: $$H(z) = (-z^{-2} -2z^{-1} +2z +z^2) (1/8T)$$
Where T is the sampling period.
Normally in MATLAB, I use fvtool
and enter coefficients but these coefficients are relevant to negative exponentials only, i.e. for a causal filter.
I want to view the magnitude response, phase response, pole zero map of an anti-causal filter in MATLAB. How is that possible?
