And because the spectrum of the discrete time signal, this similar spectrum will periodically repeat if we prolonged the frequency better beyond $f_s$ this sort of the spectrum proven can also be a similar spectrum in every single frequency band from $nf_s$ to $(n+1)f_s$ for just about any integer $n$. https://pginsector15gurugram.tech.blog/2025/07/28/safe-and-modern-pg-in-gurgaon-for-female-students-join-osmstays/
