And because the spectrum of a discrete time sign, this same spectrum will periodically repeat if we extended the frequency better beyond $f_s$ these types of that the spectrum demonstrated can be the identical spectrum in each and every frequency band from $nf_s$ to $(n+1)f_s$ for almost any integer $n$. https://boyspgsector15ingurgaon.blogspot.com/2025/07/find-ideal-boys-pg-in-gurgaon-sector-15.html
