And as the spectrum of a discrete time signal, this similar spectrum will periodically repeat if we extended the frequency better beyond $f_s$ this kind of which the spectrum shown is likewise precisely the same spectrum in each and every frequency band from $nf_s$ to $(n+one)f_s$ for any integer $n$. https://pgingurgaonsector14.food.blog/2025/07/28/top-student-friendly-pg-in-gurgaon-sector-14-only-at-osmstays/
