DFD Integer Delay VI
Owning Palette: Processing VIs
Installed With: Digital Filter Design Toolkit
Delays a signal continuously by a specified integer number of sample intervals. Wire data to the signal in input to determine the polymorphic instance to use or manually select the instance.
Use the pull-down menu to select an instance of this VI.

DFD Integer Delay (PtByPt)
 | init? controls the initialization of internal states. The default is FALSE, in which this VI initializes internal states from the final states of the previous call to the current VI instance. If you select TRUE, this VI initializes internal states to zero. | ||||||
 | signal in is the input sample you want to process. | ||||||
 | delay specifies the number of samples by which you want to delay the input signal. The default is 1. The value of delay must be greater than or equal to zero. | ||||||
 | error in describes error conditions that occur before this VI or function runs.
The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.
| ||||||
 | signal out returns the delayed sample. | ||||||
 | error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces.
Right-click the error out front panel indicator and select Explain Error from the shortcut menu for more information about the error.

DFD Integer Delay (Array)
| init? controls the initialization of internal states. The default is FALSE, in which this VI initializes internal states from the final states of the previous call to the current VI instance. If you select TRUE, this VI initializes internal states to zero. | ||||||
 | signal in specifies the input array of single-channel samples you want to process. | ||||||
| delay specifies the number of samples by which you want to delay the input signal. The default is 1. The value of delay must be greater than or equal to zero. | ||||||
| error in describes error conditions that occur before this VI or function runs.
The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out.

DFD Integer Delay (PtByPt NChan)
| init? controls the initialization of internal states. The default is FALSE, in which this VI initializes internal states from the final states of the previous call to the current VI instance. If you select TRUE, this VI initializes internal states to zero. | ||||||
