1.30 Transfer Function Block
This component models the transfer characteristic of a device, circuit or system in the s
domain. The transfer function block is specified as a fraction with polynomial numerators and
denominators. A transfer function up to the third order can be directly modeled. This
component may be used in DC, AC and transient analyses.
Characteristic Equation
This transfer function model is defined in a form of the rational function:
Transfer functions up to the third order may be modeled.
