Hi Adnan
What exactly do want to plot ?
A sync(t) function ? Or function u(t) which you gave ?

t=-linspace(-511*0.005,512*0.005,1000)
u_t=3*(sin(2*55*pi*t)-sin(2*30*pi*t))./(2*pi*t);
plot(u_t);

This doesn't help since you still divide by 0 at t=0.
If you divide out, you get what I wrote in my answer.
