% generates the input signal, i.e. defines the shape of S

function Y=input_signal(x,Tx)

    %Y=0.5*(1+sign(sin(x.*2.*pi./Tx))); % rectangular signal (initially high), periode Tx
    %Y=0.5*(1-sign(sin(x.*2.*pi./Tx))); % rectangular signal (initially low), periode Tx
    %Y=0.5*(1+(sin(x.*2.*pi./Tx)));     % Sine, periode Tx
    %Y=0.5*(1+sign(sin(x.*2.*pi./Tx))).*0.5.*(1+sign(sin(x.*2.*pi./(2*Tx))));
            % rectangular signal (with   delay between peaks), periode 2Tx

    Y=0.5*(1+(sin((x-Tx/4).*2.*pi./Tx))).*0.5.*(1+sign(sin(x.*2.*pi./(2*Tx))));
            % sine-like pulse signal  (with delay between peaks), periode 2Tx
