A method for spectral analysis of random signals implemented by means of a device for spectral analysis of random signals provides for dividing, by means of a band filtration unit (7), the white noise signals and the signals to be analyzed, respectively, into P band signals of the white noise and band signals to be analyzed. Each of the P band signals of the white noise and of the band signals to be analyzed is divided, by means of a quick Fourier transformation unit (18), into M sloping signals of the white noise and of the signals to be analyzed, after which the determination and subsequent measurement are effected of the dispersion of each of the M sloping signals of the white noise and of the signals to be analyzed. A control unit (1) is used to determine the energy spectrum readings of the random signal analyzed. |
