Abstract Horizontal voluntary eye-movements based on Gaussian random noise inputs are analyzed by way of auto-and crosscorrelation-functions and power spectra. The essential rules in applying these methods are pointed out, and the elimination of instationary trends is demonstrated. It becomes evident by these techniques that eye-tracking-movements can have a higher upper frequency limit than the movements of the corresponding target. On the other hand, they are correlated in a higher degree regarding longer delay-times. The typical delay-time of the system for processing stochastic signals is obtained by cross-correlation. The power spectra of eye-movements reveal two peaks in relation to the spectra of the target which are due to the quick saccadic components of eye-movement.
