Magnitude and Phase of a Transfer Function (mag_phase)

Magnitude and phase of a transfer function (i.e. linear system) at a specific point in the frequency domain.

mag_phase

Magnitude and phase of a transfer function (i.e. linear system) at a specific point in the frequency domain.

Syntax

[mag,phase] = mag_phase(sys,x)
[mag,phase] = mag_phase(sys,x,units)

Description

[mag,phase] = mag_phase(sys,x) returns the magnitude, mag, and phase, phase, of the linear system, sys, at a desired location x in the frequency domain. If sys represents a continuous-time transfer function , then x corresponds to a point . If sys represents a discrete-time transfer function , then x corresponds to a point . By default, the phase is returned in units of degrees.

[mag,phase] = mag_phase(sys,x,units) does the same as the syntax above, but returns the phase in degrees if units is specified as 'deg', and in radians if units is specified as 'rad'.
