I'll show you the basic concept of how to construct this 5-sec delayed square wave.
t = linspace(0, 6, 601); % 11 minus 5-sec delayed, need to generate data for nett 6 seconds
f = (2*pi)/4 % angular frequency with a period of 4 seconds
x = sin(f*t); % base function for the signum function to switch
y = 3/2*sign(x) - 1/2; % square wave function
plot(t+5, x, t+5, y) % 5-sec delayed
grid on, xlim([0 12]), ylim([-3 2]), xlabel('t'), ylabel('y(t)')
