摘要
首先 ,提出了一种从采样数据中提取信号频率的方法 ;其次 ,通过相对误差计算公式给出了此种方法的相对误差 ;且在 m atlab环境下验证了此种算法并给出了仿真结果 ,对从采样数据中提取信号频率的研究有一定的参考意义。
First, it gives a method of extracting signal frequency from sampling data Second,it also gives the range of relative errors by the relative errors formulation Finally, the theory is verified under the environment of Matlab and the results are also given The conclusion may be taken as a tutor for research of extracting signal frequency from sampling data
