I have a signal say X, when will I model it as a Random process and when as a Random variable? Modeling as a RV is ok for me, like at each n I perform an experiment and the output of the experiment is X, but I cannot understand how and why to model it as a RP? I am sorry if this too basic, but after studying a great deal about RV and RP I am still unable to figure this out. Thanks!
 

its simple to understand if you see it practically..

As example a single point is only a point but if we connect many point like that through pencil it will give some kind of design or a graph. so, that's nothing but process.


so if you have many points or take it as variables then the line which connect this all is random process which has some kind of understanding.
 

I am sorry but I am unable to understand your statements
 

ok. if you don't know then follow the book HSU, for SSA. you will get clear idea about this. if you know then its not problem.
