Canonical coordinates are uncorrelated, and quantizing and Wiener filtering are applied to each component independently.

We explore the consequences of this finding in the context of stochastic time-frequency analysis in Cohen’s class. There, the analytic signal plays a prominent role because it reduces interference terms. However, the usual time-frequency representation (TFR) based on the analytic signal gives only an incomplete signal description. It must be augmented by a complementary TFR whose properties we develop in detail.
