摘要
文章通过对 A计权、B计权和 C计权 3种噪声计权网络频率响应函数的建模 ,得出了这 3种频率计权函数的解析表达式。实际应用表明这 3种频率计权公式具有编程方便、计算精度高等优点 ,解决了窄带噪声谱数字分析系统中的频率计权问题。
In this paper, the method of three kinds of weighted networks (A,B and C weight) is established based on the study of their frequency response functions. Three weighting function expressions are derived. The practical applications show that these weighting functions have features of high calculating precision and convenient programming,and the frequency weighting problem in the narrow band noise spectrum analysis can be solved.
