Effects of digital filtering on the parameters of sinusoidal tracking eye movements.
In the present study linear nonrecursive (FIR) filters designed with the Hamming window and hybrid median filters were examined in connection with computer analysis of sinusoidal tracking eye movements. It is important that digital filters which do not distort sensitive properties of eye movement signals are employed in order to prevent changes caused by too strict filtering in average parameter values of eye movement signals, indicators of some otoneurological disorders. It turned out that within reasonable limits these filters are valid in filtering of sinusoidal tracking eye movement signals.
