How do i write the y3 for the convolution of x and h? i have the code set up already but im not sure how to write the y3

%second equation

figure

t= -2:delta:6;

x= sin(2*pi*t).*(u(t)-u(t-3));

h= u(t)-u(t-3);

y = delta*conv(x,h);

tt= -4 :delta:12;

plot(tt,y);

hold on

t = -4:0.1:12;

y3=

plot(t, y3, 'ro'); title('x(t)= sin(2*pi*t).*(u(t)-u(t-3))-> h= u(t)-u(t-3) );

legend('Approximation', 'Theoretical'); hold off

yeah but what would be the theoretical convolition of them in u(t)

You cannot generate a unit step function like what you are doing using u(t), its just a representation for unit step function.
