Recovering phase response from frequency magnitude of a minimum-phase system: Practical considerations
My problem is this: Given a frequency magnitude response $|\hat{h}(\omega)|$ of a minimum phase system, how can one reliably recover its phase response? In my case, the magnitude is quite short (~30-...
