FFT
ptolemy.domains.sdf.lib.FFT

This actor calculates the Fast Fourier Transform of a sequence of complex inputs. The order of the FFT determines the number of tokens that will be consumed and produced on each firing. The order is the base-2 logarithm of the size. The default order is 8, which means that 28 = 256 tokens are read and 28 = 256 tokens are produced. The result of the FFT is a new array of Complex tokens.

order
The order of the FFT. The type is IntToken, and the value should be greater than zero. The default value is an IntToken with value 8.
