coherence function meaning in English
相干函数
Examples
- Partial coherence function
部分相干函数 - Spatial coherence function
空间相干函数 - Initial growths of disturbances are measured by means of hot - wire anemometry . due to the detected signals with low signal to noise ratio , the coherence function is used to eliminate background noise during data reduction
在扰动增长的初始阶段，信号的信噪比非常地低，根据相关谱分析方法，应用相干函数，将扰动信号有效地提取出来，测量了初始扰动的增长。 - In analysis and transaction of signals , spectrum analyzer is a classical and important instrument which is mainly used to analyze the time domain wave , amplitude , spectrum domain wave , demodulating analysis , digital filtering , correlate analysis , transfer function and coherence function of signals
频谱分析仪是信号分析与处理中常用的仪器，它可对信号进行时域分析、幅值域分析、频域分析、解调分析、数字滤波、相关分析和传递相干分析。 - The basic concepts of second - order coherence theory in describing wavefields are introduced . these concepts are the cross - spectral density function and spectral degree of coherence in the space - frequency domain , and the mutual coherence function and the complex degree of coherence in the space - time domain
