This actor calculates the autocorrelation of a sequence of input tokens.
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).
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.
This actor calculates the Fast Fourier Transform of a sequence of complex inputs.
This actor calculates the inverse FFT of a complex input array.
