资料介绍

测试系统中经常要对实验数据进行滤波处理,理想的滤波器在实际中是做不到的,设计者只能使滤波器的性能尽量地逼近理想滤波器,获得最佳的滤波效果。在研究比较了二阶压控电路的输出曲线随通带增益变化情况的基础上,改进设计了一种互补型的四阶压控滤波器;并将它和其他几种同阶滤波器做比较,证明了它的优点。最后,用电路实现,并在MuhisimlO里仿真,验证了它的滤波效果,并给出了这种滤波器的一般设计方法。

The filtering process for experimental datum is commonly used in experiments, However, the ideal filter is impossible to realize in practice, and so one can only approximate the best filtering performance. This paper proposed a complementary fourth-order low-pass filter, based on the analysis of the outputs of the voltage-controlled circuit with different bandpass gains in second order curves. The paper illustrates its advantages by comparison of several filters with the same order.Finally, the design value after computation is obtained to define general circuit parameter. This paper comes to some valuable conclusions through the verification of the designed low-pass filter with Muhisim 10 software.
