随机信号中值频率实时估计的研究

Research on the estimating median frequency of random signal power spectrum in real time

提出了一个在线实时估计中值频率的算法．这个算法是建立在通过控制采样频率实现截止频率可调的数字滤波器的基础上．为检验算法的有效性，文中给出了输入试验信号测试结果．

An algorithm which provides on line estimation of median frequency in real time is presented in this paper. The algorithm is based on digital filters implemented by controlling the sample frequency to adjust the cut off frequency of the filters.The results are obtained from input cosine waves and white noise signal into the system.
