Abstract
Analysis of time frequency (TF) distributions, as the instantaneous frequen cy (IF) estimators for small noise, has been recently done. In this letter, we extend the analysis to high noise, This noise causes a specific error, which can dominate over ail other studied errors. The crucial parameter is the ratio of auto-term (AT) magnitude and distribution standard deviation.
