本文讨论了用TP-801单板机实现的数字式自适应噪声消除系统,提出了一种新的简单实用的μ值选取方法。为适应单板机的工作条件,本系统采用了对信号的分段处理和重复处理法。对各种不同干扰的抵消实验,充分证明了本系统的工程实用性。
This paper discusses the digital adaptive noise cancellation system implemented by TP-801 single board computer, and proposes a new simple and practical μ value selection method. In order to meet the working conditions of the single-board machine, the system uses a signal segmentation and repeat processing method. The experiments of offsetting various interferences fully proved the practicality of the system.
