| 摘 要： | 为了研究开关式电容滤波器的输出特性和频率响应,采用了连续系统时域分析方法,建立了滤波器的输出特性模型和频率响应模型,并进行了仿真。通过仿真曲线可以看出,滤波器的输出是一个逐渐稳定的迭代过程,只有当输入信号频率与开关信号频率相等时才有最大输出,证明了该滤波器具有较强的频率选择和一定的相位选择功能,其结果与实际测量结果一致。

| Abstract: | A method of time field analysis in continuous system is adopted to study the output characteristic and the frequency response of switch type capacitor filter.The mathematic models of output characteristic and frequency response are set up.The simulation results show that the output of filter is a gradually stabilized iterative process.Its maximum value can be gained only when the input signal frequency is equal to the switch signal frequency.It is proved that the filter has a strong function of frequency choice and a certain function of phase choice,and the theoretical analysis results are coincident with practical measurement. |
