how do plot x(n)=u(n-2)-u(n-5)

hello i need plot for signal x(n)=u(n-2)-u(n-5) thanks.

Answer 1

n = (-20:20);
u_n = n>=0;
u_n_2 = n>=2;
u_n_5 = n>=5;
u_diff = u_n_2 - u_n_5; 
subplot(3,1,1); stem(n,u_n_2);xlim([-15 15]); ylim([-2 2])
subplot(3,1,2); stem(n,u_n_5);xlim([-15 15]); ylim([-2 2])
subplot(3,1,3); stem(n,u_diff);xlim([-15 15]); ylim([-2 2])

X(n) = u(n) + 2u(n-1)+u(n-4)
