Abstract :
A recursive moving averager with an adaptive moving window length is proposed for on-line respiratory artefact removal in impedance rheopneumographic measurement. Results show that the residual ripples are reduced in a squared sense and hence the filtering performance is superior to conventional moving averagers.
