I am studying chapter 4 of book signal processing first
There i came across a concept which says that(what i have understood)the spectrum of continuous time signal has limited number of lines while spectrum of discrete time signal has infinite number of lines
Why?what is the reason for this difference?
above link Is snap of frequency spectrum diagrams of both continous time and discrete time signals
below link is relevant theory of book https://i.stack.imgur.com/fu8de.jpg
