Measuring frequency of received signal by a spectrum line ratio method

在声信号处理系统中,需要实时地测量接收信号的频率。文章利用谱线比值法测量接收信号的频率。该方法具有实时性好、结构简单、准确率高等优点。作者根据论文提出的方法进行了计算机的仿真研究,研究结果验证了这种方法的可行性。

In acoustic signal processing systems, it is required to measure the frequency of the received signal in real time. This paper utilizes a spectrum line ratio method to measure the frequency of the received signal for its real-time characteristic, simple structure, and high accuracy. Computer simulation is performed and the results verify the feasibility of the method.
