时频分析方法提供了时间域与频率域的联合分布信息，清楚地描述了信号频率随时间变化的关系。-Time-frequency analysis method provides a time-domain and frequency domain, the joint distribution of information that clearly describes the signal frequency versus time relationships.

基于labview的chirp信号联合时频分析，2012版本以上-Joint time-frequency analysis of chirp signal based on labview
