Abstract. An algorithm of spectral analysis of measuring signals is proposed. In contrast to algorithm of fast Fourier transform, the proposed algorithm allows excluding operations of complex multiplication in calculation of complex Fourier coefficients. Flowchart of hardware realization of the algorithm is presented, time diagram of the device operation is demostrated.
Keywords: spectral analysis, complex Fourier coefficients, calculation algorithm, function diagram, hardware realization
