And As the spectrum of a discrete time signal, this exact spectrum will periodically repeat if we extended the frequency bigger beyond $f_s$ this sort of which the spectrum revealed is also exactly the same spectrum in just about every frequency band from $nf_s$ to $(n+one)f_s$ for any integer $n$. https://boyspggurgaonsector15.family.blog/2025/07/29/trusted-girls-pg-in-gurgaon-sector-15-with-study-first-environment/
