Figures - available via license: Creative Commons Attribution 3.0 Unported WebThe Wigner–Ville distribution is a quadratic form that measures a local time-frequency energy given by: (,) = (+) ()The Wigner–Ville distribution remains real as it is the fourier transform of f(u + τ/2)·f*(u − τ/2), which has Hermitian symmetry in τ.It can also be written as a frequency integration by applying the Parseval formula:
Webbution belonging to Cohen’s class. One common kernel is the Choi-Williams kernel φ(v,τ) = e−v 2τ /σ. Determine analytically the Choi-Williams time-frequency distribution for the signal x(t) above. To illustrate the different distributions and their properties we will use both the theoretical results from above and numerical calculations.
