And as the spectrum of the discrete time signal, this identical spectrum will periodically repeat if we extended the frequency greater over and above $f_s$ these types of the spectrum demonstrated can be the identical spectrum in each frequency band from $nf_s$ to $(n+one)f_s$ for just about any integer $n$. https://boyspggurgaonsector15.blogspot.com/2025/07/well-maintained-boys-pg-in-gurgaon.html
