IFFT
ptolemy.domains.sdf.lib.IFFT

This actor calculates the inverse FFT of a complex input array. The order of the IFFT 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 IFFT is a new array of Complex tokens.

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