$$f(t) = \mathcal{F}^{-1}\{F(\omega)\} = \frac{1}{2\pi} \int_{-\infty}^{\infty} F(\omega) e^{i \omega t} \, d\omega$$

Un VLAN (Virtual Local Area Network) est un réseau local virtuel qui permet de segmenter un réseau physique en plusieurs sous-réseaux logiques. Il fonctionne au niveau 2 du modèle OSI (couche liaison de données) et permet d’isoler des groupes d’appareils, même s’ils sont connectés à la même infrastructure physique (comme un switch).

Signal-to-Noise Ratio (SNR):
Measure before/after denoising.
Formula:$$
\[
\text{SNR (dB)} = 10 \log_{10} \left( \frac{P_{\text{signal}}}{P_{\text{noise}}} \right)
\]$$
