象的时变数字信号瞬时频率枯计方法。这种方法利用时频分析结果来估计信号的麟时频率，其

中涉及时频分析、滤波、曲线拟合辞多种处理过程。处理过程的编程实现封较于用户界面上作

为文互工具的控件中，由用户通过交互界面逐步完成估计瞬时预率的工作.-Tsuen introduced a digital signal processing in the MATLAB toolbox, MATLAB and MATLAB data analysis of ring-shaped object digital signal time-varying instantaneous frequency of dry method. This method using the results of time-frequency analysis to estimate the signal frequency CHU, which involves time-frequency analysis, filtering, curve fitting a variety of speech processing. Programming process to achieve closure on the user interface than the text of each other as a control tool, by the user interface step by step through the completion of pre-estimated instantaneous rate of work.
