And as the spectrum of the discrete time sign, this same spectrum will periodically repeat if we extended the frequency bigger beyond $f_s$ these kinds of which the spectrum shown can also be the identical spectrum in every single frequency band from $nf_s$ to $(n+one)f_s$ for almost any integer $n$. https://girlspgsector15part2gurgaon.video.blog/2025/07/29/trusted-girls-pg-in-gurgaon-sector-15-with-study-first-environment/
