1. (a) To represent the discrete-time signal

x[n] ={

generate the index vector ‘n’ and signal vector ‘x’. Plot this signal by using function ‘stem’ and several commands to help you label plots appropriately, as well as to print them out. You only need to type ‘help stem’ to understand how it works on your system. (commands : xlabel, ylabel, title, axis,grid,…)

n=-3:1:3;
x=2*n;
stem(n,x);
xlabel(`n`);
ylabel(`x[n]=2*n`);
title(`represent the discrete-time signal`);
axis([-5 5 -8 8]);
grid on;







(b) Sinusoids and complex exponentials can also be generated using ‘cos’, ‘sin’ and ‘exp’. Generate the complex-valued signal
