And Because the spectrum of the discrete time signal, this similar spectrum will periodically repeat if we extended the frequency better further than $f_s$ this kind of the spectrum shown is likewise exactly the same spectrum in every single frequency band from $nf_s$ to $(n+1)f_s$ for virtually any integer $n$. https://boyspggurgaonsector15.family.blog/2025/07/29/trusted-girls-pg-in-gurgaon-sector-15-with-study-first-environment/
