Abstract
We give a brief review of ideas and insights derived from the study and application of positive time-frequency distributions, in the nearly 25 years since their formulation by Cohen, Posch and Zaparovanny. Associated topics discussed include instantaneous frequency and conditional moments, the "time varying spectrum" and joint versus conditional distributions, the uncertainty principle, kernel design, cross terms, AM-FM signal decompositions, among others. Many of the conventionally held ideas in time-frequency analysis are challenged by results from positive time-frequency distributions.
