DynamicSystems[FrequencyResponse] - compute the frequency response of a system

Calling Sequence

FrequencyResponse(sys, opts)

Parameters

sys

-

System

opts

-

(optional) equation(s) of the form option = value; specify options for the FrequencyResponse command

Description

• 

The FrequencyResponse command computes the frequency response of subsystems of sys, a system object.

• 

If sys is a continuous system, its s-domain transfer function is computed and then converted to the real frequency domain using the transformation s -> I*omega, where omega is the angular frequency.

• 

If sys is a discrete system, its z-domain transfer function is computed and then converted to the real frequency domain using the transformation z -> exp(I*omega*Ts), where omega is the angular frequency and Ts is the sample time.
