[Spectrum analysis of vestibular nystagmus].

A procedure for the spectral analysis of nystagmograms obtained by rotary stimulation with the rate of 180 degrees/s for 20 s has been developed with the aim to reveal the most typical changes in the vestibular nystagmus with one or another form of the cochleovestibular pathology. A signal recorded in the analogous form was processed by computer EC-1022. Periodograms were calculated by the method of the fast Fourier transform and periodogram smoothing by averaging of realization sites.

[Automated analysis of vestibular nystagmus].

The method of electronystagmogram (ENG) analysis by a computer is described. ENG-signals received in the course of caloric or rotatory examinations are processed by a computer after tape recording and analog-to-digital converting. The algorithm allows main parameters of the nystagmic response to be computed in a more effective and powerful way as compared to non-computer methods.
