... is determined, and the ranking of risk failure stations is obtained so as to find out the serious failure process and stations. The spectrum analysis method is used to identify the fault data and judge the “abnormal” value in the fault data. Based on the analysis of the impact, an “offset operator” is designed...

... average operator of N items is selected based on spectral characteristics to eliminate the influence of periodic factors and noise. Findings Through the spectrum analysis of the real-time data sensed and recorded by microwave sensors, the spectral characteristics and the ranges of information...

.... The unique methods in digital signal processing systems “spectrum analysis” of AGO/IAGO are carried out in the frequency domain. Findings Through the theoretical study and practical example, benefit of spectrum analysis is explained, and the mechanism and filter efficacy of AGO/IAGO are quantitatively...
