DAPL DSP -- Spectral Analysis

DAPL includes over 100 built-in commands in the following categories.

FFT and FFT32 (parameters): Calculates fast Fourier transforms of blocks of data. Parameter options allow forward and backward transforms, real or complex data, word or long data, window functions, and block sizes as large as 16,384 points. The FFT command emphasizes faster computations; the FFT32 command emphasizes higher numerical precision.
CORRELATE (parameters): Calculates correlations between blocks of data.
CROSSPOWER (parameters): Calculates crosspower spectra of blocks of data.
TFUNCTION1 (parameters): Calculates amplitude and phase of transfer functions from two channels of Fourier transform data.
