Fast Fourier analysis and synthesis system - has Fourier transformer with Fourier processor having independent input and outputs

摘要

In the fast Fourier processor, Fourier analysis of the first signals and Fourier synthesis of the second signals takes place in brief alternation. The same fast fourier processor is used for Fourier analysis and Fourier synthesis and has the same linking instruction and the same store with the same coefficient. A sorting device controlled by the word cycle of the input signals of the processor separates the components of the signals generated by Fourier analysis from the components of the signals generated by Fourier synthesis. The sorting device also arranges the sequences of the signal components.
