Description of Fourier :
The unit FOURIER contains the fast Fourier transform (FFT) component TFastFourier which can be installed into the VCL. TFastFourier can transform data sets of up to 32k samples in both directions and provides several of the most important windowing functions (such as Hamming, Blackman, Cosine Square, Triangle, and others). Sources are available separately.
