Abstract :
This paper addresses a Volterra series representation of bilinear (or quadratic) time-frequency distributions that belong to Cohen´s class, whereby the analogy of the bilinear class with a second-order double Volterra series is utilized. In addition, a different viewpoint for the bilinear kernel and a complementary interpretation concerning the quadratic time-frequency distributions are provided.
