用单片微机实现自适应滤波——自适应噪声抵消系统(ANCS)

Using Single-chip Computer to Realize Adaptive Filtering - Adaptive Noise Cancellation System ANCS

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 work of using single-chip computer to realize real-time adaptive filtering, emphatically discussing cancellation of 50 Hz interference which is called adaptive noise cancellation.It includes the research work of possibility of using Apple-II to realize analog adaptive filtering, the introduction of the software and hardware system of using MCS-51 to realize ANSC.This paper has reference value to adaptive research, application and teachsng experiment of adaptive filtersng.
