The Nyquist [[Frequency]] of some [[Sampling]] is half the sampling frequency. $\huge f_{\mathcal{N}} = \frac{f_{s}}{2} $ ![[Pasted image 20260922143531.png|invert_Sepia]] The nyquist frequency represents what frequency in which aliases are symmetric over. $\huge f(\omega_{0}) = f(\omega_{s} - \omega_{0}) $
