There are several types of noise that are commonly analyzed in noise spectroscopy:
Thermal Noise: Also known as Johnson-Nyquist noise, it arises from the random motion of electrons due to temperature. 1/f Noise: Also known as flicker noise, it is characterized by a power spectral density that is inversely proportional to frequency. Shot Noise: This arises due to the discrete nature of charge carriers (electrons) and is prominent in nano-scale devices. Quantum Noise: Originates from quantum mechanical effects and is significant in ultra-small structures.
