Ive heard both of these terms and i am still having trouble to understand what is the difference between these two. As far as i understood, the only difference between discrete and discretized signal, is the x axis of it, for example if i have a single dirac at the $\Omega_0$ frequency it is considered to be discretized signal if its x axis has $\Omega$ as a variable
However, if we want to make this a discrete signal, we need to somehow manipulate the value on the x-axis (normally we should have n at the x axis if we want to have discrete signal).
I hope that question wasn't confusing. Any help appreciated!
What if i have a discretized signal, how am i supposed to make discrete signal out of it?
