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

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