time frequency signal representation的意思|示意

Now we have a true time-frequency representation of the signal.

现在我们有了信号的一个时频表示。

The Doppler blood flow signal is inherently a nonstationary Gaussian random process whose time-frequency representation associates with the time-varying velocity of blood flow and its variations.

多普勒超声血流信号是一个非平稳的高斯随机过程，其时频分布与血流的速度及其变化有密切的关系。

An improved algorithm for calculating the signal-dependent adaptive kernel time-frequency distribution is put forward based on the radially-Gaussian signal dependent representation.

通过对基于信号特征的径向高斯核时频分布进行改进，提出了一种基于信号特征的自适应核时频分布的改进算法。

A method of signal time-frequency representation with phase factor is introduced.
