And because the spectrum of a discrete time signal, this similar spectrum will periodically repeat if we prolonged the frequency greater past $f_s$ this sort of which the spectrum demonstrated is additionally precisely the same spectrum in each and every frequency band from $nf_s$ to $(n+1)f_s$ for almost any integer https://girlspgingurgaonsector15.car.blog/2025/07/28/find-your-ideal-pg-in-sector-14-gurgaon-with-osmstays/
