Class  Description 

Autocorrelation 
This actor calculates the autocorrelation of a sequence of input tokens.

Chop 
This actor reads a sequence of input tokens of any type, and writes a
sequence of tokens constructed from the input sequence (possibly
supplemented with zeros).

DelayLine 
This actor reads tokens from its input port, and for each token read
outputs an array that contains the current token as the first token,
followed by some number of previously read tokens.

FFT 
This actor calculates the Fast Fourier Transform of a sequence of
complex inputs.

IFFT 
This actor calculates the inverse FFT of a complex input array.
