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
	Ortskurve	Displays the curve 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
	Complex functions	Displays functions of the type f(z,param) in the complex plane.
