CD Verify if Discrete VI
Owning Palette: Model Information VIs
Requires: Control Design and Simulation Module
Checks if the input model represents a discrete-time system. Wire data to the State-Space Model input to determine the polymorphic instance to use or manually select the instance.
CD Verify if Discrete (State-Space)

![]() |
State-Space Model contains a mathematical representation of and information about a system that this VI checks to determine if it represents a discrete-time system. |
![]() |
If Discrete? is TRUE, the model represents a discrete-time system and the Sampling Time of the model is greater than zero. |
![]() |
Sampling Time returns the sampling time of the model. Sampling Time defines whether the model represents a continuous-time system or a discrete-time system. If the model represents a continuous-time system, Sampling Time equals zero. If the model represents a discrete-time system, Sampling Time is greater than zero and equal to the sampling rate, in seconds, of the discrete system. |
CD Verify if Discrete (Transfer Function)

![]() |
Transfer Function Model contains a mathematical representation of and information about the system that this VI checks to determine if it represents a discrete-time system. |
![]() |
If Discrete? is TRUE, the model represents a discrete-time system and the Sampling Time of the model is greater than zero. |
![]() |
Sampling Time returns the sampling time of the model. Sampling Time defines whether the model represents a continuous-time system or a discrete-time system. If the model represents a continuous-time system, Sampling Time equals zero. If the model represents a discrete-time system, Sampling Time is greater than zero and equal to the sampling rate, in seconds, of the discrete system. |
CD Verify if Discrete (Zero-Pole-Gain)

![]() |
Zero-Pole-Gain Model contains a mathematical representation of and information about a system that this VI checks to determine if it represents a discrete-time system. |
![]() |
If Discrete? is TRUE, the model represents a discrete-time system and the Sampling Time of the model is greater than zero. |
![]() |
Sampling Time returns the sampling time of the model. Sampling Time defines whether the model represents a continuous-time system or a discrete-time system. If the model represents a continuous-time system, Sampling Time equals zero. If the model represents a discrete-time system, Sampling Time is greater than zero and equal to the sampling rate, in seconds, of the discrete system. |
