Effects of digital filtering on the parameters of impulse-like eye movements.

Influence of two filtering modes were researched with electro-oculographically recorded impulse-like eye movements. Linear finite impulse response (FIR) and non-linear hybrid median filters were explored by considering gain and latency parameters that yield the most important information in the case of these eye movements. It is stated that carefully selected lowpass filtering can securely be run without considerable changes in parameter values in order to discard noise stemming from physiological or other reasons.
