倒频谱分析 meaning in Chinese

cepstrum analysis

The inverse spectrum analysis of rolling bearing fault
滚动轴承故障的倒频谱分析
It is stressed in this paper the analysis methods used in vibration faults of average power spectrum and cepstrum , based on the fast fourier transform algorithm , and development of the vibration signal analysis system in test - driving of wj6 engine , involved the technic of software or hardware
文章重点给出基于fft技术的功率谱和倒频谱分析方法、振动信号分析系统的设计和实现，讨论了相应软件开发中所涉及的技术问题。
The signal process function of the software include these function : digital filter , windowing , auto - correlation function and cross - correlation function , mean and variance , probability density function and probability distribution function statistic ; auto - power spectrum , cross - power spectrum , frequency response function , coherence function , cepstrum analysis based on fft ( fast fourier transfer ) ; joint time - frequency analysis based on stft ( short - time fourier transfer )
软件的处理功能包括：数字滤波、时域加窗、自相关与互相关处理、均值和方差计算、概率密度和概率分布函数计算；在快速傅立叶变换( fft )基础上计算自功率谱、互功率谱、频率响应函数、相干函数、倒频谱分析；基于短时傅立叶变换( stft )的联合时频分析等。
