    Generates a signal containing a sinc pattern.

    amplitude

    Amplitude of the pattern.

    Default: 1

    datatype_icon

    delay

    Shifts the peak value within the output pattern as the node generates the pattern. The peak value of the output pattern occurs at the index value i = delay/(dt).

    Default: 0

    datatype_icon

    error in

    Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

    Default: No error

    datatype_icon

    dt

    Sampling interval. This floating-point number is inversely proportional to the width of the main sinc lobe. That is, the smaller the sampling interval, the wider the main lobe; the larger the sampling interval, the smaller the main lobe. When this input is 1 and delay is an integer value, this node sets the output pattern to zero except at the point where i = delay. At this point, the value is equal to amplitude. The recommended range of values for the sampling interval is between 0 and 1. This input must be greater than 0. If this input is less than or equal to zero, this node sets the output pattern to an empty array and returns an error.

    Default: 0.1

    datatype_icon

    samples

    Number of samples in the pattern. This input must be greater than or equal to 0. If this input is less than zero, the node sets the output pattern to an empty array and returns an error.

    Default: 128

    datatype_icon

    sinc pattern

    Output sinc pattern. The largest output pattern this node can generate depends on the amount of memory in your system and is theoretically limited to 2,147,483,647 (231 - 1) elements.

    datatype_icon

    error out

    Error information. The node produces this output according to standard error behavior.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported
