Adaptive sliding bandlimited multiple fourier linear combiner for estimation of pathological tremor
The analysis of frequency characteristic of physiological and pathological tremor is proposed. The algorithm incorporates Butterworth filter, WFLC, frequency modulation block and BMFLC. The method could estimate desired signals with sliding frequency band and zero-phase lag. One mechanical platform for simulating tremor and intention movements is developed. The method successfully extracts the voluntary motion from the raw measured signal.
