The Application of Adaptive Cancelling Method in Electrogastrographic Signal Processing 自适应抵消方法在胃电信号处理中的应用
This paper puts emphasis on the research of the antenna sidelobe adaptive cancelling technology combining closely with the science R& D of signal processor of some type of radar control and guide station. 本论文紧密结合某型号雷达制导站信号处理机的研制与开发,重点对天线旁瓣自适应相消技术进行了研究。
The function principle of vibrating platform is introduced, then a new approach of noise cancelling is presented on the basis of different features of the wavelet transformation of signal edge and noise, at last the effect of the approach used is given and discussed too. 介绍振动台的工作原理,提出一种利用信号边沿与噪声的小波变换的不同性质来去噪的方法,给出该方法的使用效果,并进行了讨论。
Adaptive noise cancelling system of ask signal corrupted by noise ASK混噪信号的自适应消噪系统
Aimed at noise cancelling cut for ultrasonic inspecting signal of seabed oil pipeline flaw, a kind of noise cancellation method based on wavelet analysis is studied. 针对海底石油管道超声检测信号的噪声消除问题,本文研究了基于小波分析的噪声消除方法。
