Dear all, I have my code for calculating delay time for signals.. I have two signals and I calculated the delay time.I plotted both signals in the graph using subplot.When I run it I get the delay time, If the delay is positive then Y (second signal) must be the delayed signal otherwise X is delayed one. I am trying to plot the delayed signal on the same graph as the one that is not delayed. So I used if-statement to represent the two cases, e.g if delay is 5 then I need to plot (Y+5)on the same plot as X. My difficulty is by saying in the if-statement that if it positive add it to Y AND plot it in the same graph ?
x = sample1(:,1);X = (x).';y = sample2(:,1);Y = (y).';figure;clfsubplot(3,1,1);[xi,f]=ksdensity(X); plot(f,xi); line(repmat(X,2,1),repmat([0;0.1*max(xi)],1,length(X)),'color','r' ); subplot(3,1,2);[xi,f]=ksdensity(Y); plot(f,xi); line(repmat(Y,2,1),repmat([0;0.1*max(xi)],1,length(Y)),'color','r' );[Rxx,lags] = xcorr(X,Y);[Z,delay] = max(Rxx);lags(delay);
% If the delay is positive then Y is the delayed Signal, otherwise is X the delayed Signal.
if delay>0 hold [xi,f]=ksdensity(Y+delay); plot(f,xi);else hold [xi,f]=ksdensity(X+delay); plot(f,xi);end
Thank you
