摘要:
针对接收机电磁传导干扰问题,分析了中频滤波器的带通特性,选用汉宁窗函数,便于选取任意频率间隔的中频特性,其次通过快速傅里叶变换得到频域特性,再将此信号进行快速傅里叶逆变换得到时域最大值; 最后对通过快速傅里叶变换得到的离散频域信号进行最大值和平均值检测. 仿真结果表明,所提方法可以有效实现EMI接收机检波器模型的搭建.
Abstract:
In this paper,the band-pass characteristics of IF filters are analyzed for EMI problems in receivers. With Hanning window function,it is easy to select the intermediate frequency characteristic of any frequency interval. Then the frequency domain characteristics are obtained by fast Fourier transform,and then the fast Fourier inverse transform is used to obtain the maximum value in time domain. Finally,the maximum and average values of the discrete frequency domain signals obtained by fast Fourier transform are detected. Simulation results show that the proposed method can effectively build the EMI receiver geophone model.
