Wigner distribution

Wigner distribution or Wigner function may refer to:


 * Wigner quasiprobability distribution (what is most commonly intended by term "Wigner function"): a quasiprobability distribution used in quantum physics, also known at the Wigner-Ville distribution
 * Wigner distribution function, used in signal processing, which is the time-frequency variant of the Wigner quasiprobability distribution
 * Modified Wigner distribution function, used in signal processing
 * Wigner semicircle distribution, a probability function used in mathematics
