Abstract
The invention pertains mainly to a processor for the calculation of the discrete Fourier transform, comprising a real-time testing device. The device according to the invention uses the theorem of Parseval to ascertain that the processor is working properly. The device according to the invention uses, for example, an adder and a multiplier to calculate either the discrete Fourier transform or the members of the equation. Thus, by using temporal redundancy, the complexity, area and price of the processor are reduced. The invention is applied mainly to the calculation of spectra.
