Shot noise or Poisson noise is a type of noise which can be modeled by a Poisson process. In electronics shot noise originates from the discrete nature of electric charge. Shot noise also occurs in photon counting in optical devices, where shot noise is associated with the particle nature of light. See more In a statistical experiment such as tossing a fair coin and counting the occurrences of heads and tails, the numbers of heads and tails after many throws will differ by only a tiny percentage, while after only a few throws outcomes … See more Electronic devices Shot noise in electronic circuits consists of random fluctuations of DC current, which is due to electric current being the flow of discrete charges (electrons). Because the electron has such a tiny charge, however, … See more • Johnson–Nyquist noise or thermal noise • 1/f noise • Burst noise • Contact resistance See more WebOct 14, 2012 · Here we demonstrate noise suppression below the shot-noise limit in optical frequencies for relativistic electron beams.
