Signal Generation Functions
Owning Palette: Simulation VIs and Functions
Installed With: Control Design and Simulation Module. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.
Use the Signal Generation functions to generate specific waveform patterns and to index signals into an array.
 | Note If you configure a parameter for a Signal Generation function programmatically, the function updates its output value using only the current parameters and ignores the previous parameters. If you change the function parameters while the ordinary differential equation (ODE) solver is evaluating the simulation, you might introduce a discontinuity into the generated signal. |
The functions on this palette can return general LabVIEW error codes or specific Simulation error codes. If you use the functions on this palette in a Simulation Loop, LabVIEW sends any errors that these functions return to the Error output on the Output Node of the Simulation Loop.
| Palette Object | Description |
|---|---|
| Chirp Signal | Generates the point-by-point value of a chirp signal. |
| Indexer | Indexes a waveform or array by the current simulation time. |
| Pulse Signal | Generates the point-by-point value of a pulse train signal. A pulse train signal is a signal whose value switches between zero and a specified amplitude. The current value depends on the current simulation time. |
| Ramp Signal | Generates the point-by-point value of a ramp signal. |
| Signal Generator | Generates the point-by-point value of a periodic signal. |
| Simulation Time | Returns the current simulation time. This value is useful if you terminate the simulation before the final time and you want to know the time at which the simulation terminated. This value also is useful if you want to generate a signal based upon the simulation time without using the Signal Generation functions. This function does not have a configuration dialog box. |
| Sine Signal | Generates the point-by-point value of a sine signal. |
| Step Signal | Generates the point-by-point value of a step signal. |
