Figure 4
A flowchart of the conceptual core of the Scatman in numerical form is shown. Yellow blocks indicate I/O operations. Green blocks contain data preparation. The main loop of the program, which carries out the majority of calculations, is highlighted in blue. Each block contains a pseudo-code schematically showing the numerical calculation. The abbreviation DFT stands for discrete Fourier transform, practically computed through the fast Fourier transform algorithm (Cooley & Tukey, 1965). |
