time frequency resolution

It can get not only high time-frequency resolution, but also parametric description of all kinds of data structures.

它不仅可以获得较好的时频分辨率，而且可以参数化描述任何类型的数据。

DDS (direct digital synthesis) is a sort of frequency synthesis technique, which has advantages such as short frequency conversion time, high resolution in frequencies, programmability and so on.

直接数字频率合成(DDS)技术是目前广为应用的一项频率合成技术，它具有频率转换时间短、频率分辨率高、可编程等特点。

Bilinear time-frequency transform possesses a high resolution both in the time domain and the frequency domain. It can be utilized to detect weak transient signal in complex background.

双线性时间-频率变换在时间域与频率域都具有较高的分辨率，有利于复杂背景条件下微弱瞬时信号的探测。
