摘要
提出一种新型的基于曲线拟合技术的频率特性测量算法。与其它测量方法相比, 当输出信号中含有高斯噪声及高次谐波时, 该方法能有效地提高测量精度。仿真结果表明了该方法的有效性。
A novel measuring algorithms of frequency characteristic by using curve fitting techniques was presented.In comparison with other method,the proposed algorithms can effectively improve the measuring precision in the presence of Gauss noise and harmonic disturbance.Simulation results show the effectiveness of the proposed scheme.
