System functions
This graphing function allows you to display the different parameters of system functions. System functions are functions that represent the output value of a mechanical or electrical system as a complex function of the input value. Such functions can be obtained, for example, by Fourier or Laplace transformation from the differential equation of a system.
| Symbol | Graphics | Description |
|---|---|---|
 | Nyquist Plot | Displays the Nyquist Plot of the system function on the imaginary axis. The curve provides information about the stability behaviour of the system |
 | Frequency response | Represents the amplitude response, frequency response and phase response of the system function on the imaginary axis above a frequency axis. This provides information about the behaviour of the system at different frequencies. |
 | One-dimensional FFT | Plots the Fourier transforms of arbitrary functions. |
 | Complex functions | Displays functions of the type f(z,param) in the complex plane. |
