- Opis:
- The subject of the paper is the application of digital signal processing (DSP) to nonlinear hydroacoustic, acoustic and mechanic phenomena investigations. To provide such investigations a spectrum analyzer with additional functions of polyspectra and virtual input channel is proposed. The mathematics, equipment and programming of the analyzer are discussed. It is shown how the analyzer enables to detect and to explore the random impulse sequences combined with one another and with Gaussian noise, to separate the oscillations having close unstable frequencies, to observe the nonlinear interaction between oscillation modes, to detect the noise emission accompanying the oscillation mode energy dissipation.
