s2=sin((1:T)*(2*pi)/T);% vector : sine of the elements (1:T)*(2*pi)/T	
%s2=cos((1:T)*(2*pi)/T);% vector : cosine of the elements (1:T)*(2*pi)/T
%s2=sawtooth(1:T);	% vector : sawtooth wave (length T)
%s2=sinc(1:T);		% vector : sinc of the elements 1:T
%s2=square(1:T);	% vector : square wave (length T)

% normalisation
s2=s2-mean(s2);
s2=s2/std(s2);
