摘要

本文给出了如何构造适应于给定时频能量分布的积分算子。相函数，是经典傅里叶变换的相t的扩展，使得构造一个积分算子成为可能。当偏导数/ t为信号的瞬时频率时，该变换适用。

Optimal transforms related to path in the time-frequency plane

This paper shows how to construct integral operators adapted to a given time-frequency energy distribution. The phase function, which is an extension of the phase omega t of the classical Fourier transform, makes it possible to construct an integral operator. The transform is adapted when the partial derivative delta phi / delta t is the instantaneous frequency of the signal.<>
