And because the spectrum of the discrete time sign, this similar spectrum will periodically repeat if we extended the frequency better further than $f_s$ these kinds of that the spectrum demonstrated can be precisely the same spectrum in each frequency band from $nf_s$ to $(n+1)f_s$ for virtually any integer $n$. https://boyspgingurgaonsector15.sport.blog/2025/07/28/find-your-ideal-pg-in-sector-14-gurgaon-with-osmstays/
