function [zfSig]=zeroFreqFilter(wav,fs,winLength) dwav=diff(wav); dwav(end+1)=dwav(end); dwav=dwav/max(abs(dwav)); N=length(dwav); zfSig=cumsum(cumsum(cumsum(cumsum(dwav)))); winLength=round(winLength*fs/1000); zfSig=remTrend(zfSig,winLength); zfSig=remTrend(zfSig,winLength); zfSig=remTrend(zfSig,winLength); zfSig(N-winLength*2:N)=0; zfSig(1:winLength*2)=0; function [out]=remTrend(sig,winSize)
window=ones(winSize,1); rm=conv(sig,window); rm=rm(winSize/2:length(rm)-winSize/2);
norm=conv(ones(size(sig)),window); norm=norm(winSize/2:length(norm)-winSize/2);
rm=rm./norm; out=sig-rm; return;
