A maximum-phase system is the opposite of a minimum phase system. A causal and stable LTI system is a maximum-phase system if its inverse is causal and unstable. That is, 1  The zeros of the discrete-time system are outside the unit circle.
An example of series RLC circuit and respective phasor diagram for a specific Ï. In physics and engineering, a phasor (a portmanteau of phase vector), is a complex number representing a sinusoidal function whose amplitude (A), angular frequency (Ï), and initial phase (Î¸) are time-invariant.
