Fundamental Noise Sources
Fotodectors are affected by various noises, including thermal noise, shot noise, and flycker noise. Itifying mitigating these sources is crucilas for optimis deicee perforce.
Thermal Noise and Its Calculation
Thermal noise, also known as Johnson- Nyquist noise, arises fam the random motion of electronos en resistive components.
