not sure what this code mean.

i looked evrey where to find what dose this code mean and i didnt understand it

u should mean modulation index

but s = c + u*m.*c; i have no idea what this means.

thank you

u = 0.5;

s = c + u*m.*c;

figure;

plot(t,s,'linewidth',2);grid on;xlabel('time');ylabel('Amplitude');

title('AM signal');

thank you

Take m and multiply it element-by-element times c. Then multiply by 0.5 and add it in to the original c to get a new c.

Now you know the value of putting comments into your code. I'm sure you will now put comments into all your code and not make the mistake the original author did by writing code with no comments, assuming that everyone will know what he intended.

In fact @Steven Lord recommends that you write the comments first, and then add the code in afterwards.

"add it in to the original c to get a new c"

add it to the original c to get s.
