datatype_icon

input

Input values to transform.

On the host, the default data type of this input is complex double-precision floating-point.

datatype_icon

output

Result of the transform.

On the host, the default data type of this input is complex double-precision floating-point.

If you configure the node to add a cyclic prefix of length N, the first N samples are prefix values.
