| Abstract: | The spectra of in dynamic thrust measurement always overlay with the measuring signal,which degrades the performance of classical analog and digital filters. Due to the ability to adjust its parameters automatically,the adaptive filter,based on the least mean square (LMS) algorithm,requires little or no prior knowledge of the signal and the noises. In this paper,several kinds of adaptive filters are adopted to realize noise canceling,signal enhancement and periodic signal extraction according to different s... |
