| Summary: | 碩士 === 國立彰化師範大學 === 機電工程學系 === 102 === The antenna of the study is a portable coil which is used to sense the orientation of the electromagnetic pulse (EMP). A peak detector with feedback is employed to catch the information by detecting the peak voltages in the signal and the resonant circuits are engaged to select specific broadbands.
Through the Hilbert–Huang transform (HHT) and Ensemble EMD(EEMD), the information and signal caught by the peak detector and resonant circuits are extracted and decomposed into a number of intrinsic mode functions(IMFs). The decomposed IMFs representing the data set are further defined as shown in figures.
