And because the spectrum of the discrete time sign, this similar spectrum will periodically repeat if we extended the frequency larger further than $f_s$ these that the spectrum proven is also the identical spectrum in just about every frequency band from $nf_s$ to $(n+1)f_s$ for almost any integer $n$.
