本文主要介绍了用单片微机实时实现自适应滤波的研究,着重讨论了对50Hz干扰的消去——自适应噪声抵消.文中包括用APPLEII模拟自适应滤波实现的可能性研究,用MCS-51实现ANCS软硬件的介绍.本文对自适应滤波的研究和实用以及教学实验均有一定的参考价值.
This paper mainly introduces the research of real time real-time adaptive filtering using single-chip microcomputer, and discusses the elimination-adaptive noise cancellation of 50Hz interference.The paper includes the possibility of using APPLEII to simulate adaptive filtering and MCS-51 ANCS hardware and software introduction.In this paper, the research and practical application of adaptive filtering and teaching experiments have some reference value.
