This report describes a method to analyse the vestibular system when subjected to a pseudorandom angular velocity input. A sum of sinusoids (pseudorandom) input lends itself to analysis by linear frequency methods. Resultant horizontal ocular movements were digitized, filtered and transformed into the frequency domain. Programs were developed and evaluated to obtain the auto spectra of input stimulus and resultant ocular response, cross spectra, the estimated vestibular-ocular system transfer function gain and phase, and coherence function between stimulus and response functions.
本报告描述了一种在受到伪随机角速度输入时分析前庭系统的方法。正弦波之和（伪随机）输入适合用线性频率方法进行分析。将由此产生的水平眼动进行数字化、滤波并转换到频域。开发并评估了一些程序，以获得输入刺激和由此产生的眼动反应的自谱、互谱、估计的前庭眼系统传递函数增益和相位，以及刺激函数和反应函数之间的相干函数。
