This paper presents a new algorithm to extract the fetal ECG from an ECG recorded on the mother’s abdomen. The algorithm consists of two steps: first, ECG of fetus is extracted from the original signal using a two-level wavelet transform. We use Daubechie wavelet transform, which is similar in shape to heart beat wave. The resulted signal is then low-pass filtered using the Savitzky-Golay smoothing filter to attenuate the effect of noise. The filtered signal is considered as the fetal ECG. The algorithm was applied on both synthetic and real ECG signals. The results in this paper show that the proposed algorithm has promising performance.

考察一个在热循环中的表面贴片电阻。一般情况下，连接贴片电阻与电极的焊点是其中最薄弱的环节，它通常对温度和时间表现出较强的非线性。为了确保结构的完整性，基于蠕变应变和耗散能进行了疲劳分析。(This case study of a surface patch resistance in a thermal cycle. In general, the solder joint is the weakest link, which usually shows strong nonlinearity in temperature and time. In order to ensure the integrity of the structure, the fatigue analysis is carried out based on the creep strain and dissipation energy.)
