Class FFT

• public class FFT
• extends SDFTransformer

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

public VisualSim.data.expr.Parameter 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.
