Abstract

Certain biquad filters structures are characterized by a reduction of the attenuation at higher frequencies, caused by the finite value of the output resistance of the operational amplifier. In this paper, the design of the combined BP filter without the described decreasing is discussed for which one possible solution is to replace one of the biquads with another biquad that does not have this property. The result is a combined filter from different structures. The methodology to design a combined BP filter without the described decreasing is described in detail with the parameters of such biquads. The results of the proposed numerical procedure are verified by computer simulation, for this purpose a SPICE-like program MC-10 is used.

减少幅值响应衰减下降的组合滤波器设计

某些双二阶滤波器结构的特征在于，由运算放大器的输出电阻的有限值引起的在较高频率下的衰减减小。在本文中，讨论了没有所描述的递减的组合BP滤波器的设计，其中一种可能的解决方案是用另一个不具有这种性质的双四边形替换其中一个双四边形。结果是来自不同结构的组合滤波器。利用这种双四边形的参数，详细描述了在没有所述递减的情况下设计组合BP滤波器的方法。通过计算机模拟验证了所提出的数值程序的结果，为此使用了类似SPICE的程序MC-10。

期刊介绍： WSEAS Transactions on Systems and Control publishes original research papers relating to systems theory and automatic control. We aim to bring important work to a wide international audience and therefore only publish papers of exceptional scientific value that advance our understanding of these particular areas. The research presented must transcend the limits of case studies, while both experimental and theoretical studies are accepted. It is a multi-disciplinary journal and therefore its content mirrors the diverse interests and approaches of scholars involved with systems theory, dynamical systems, linear and non-linear control, intelligent control, robotics and related areas. We also welcome scholarly contributions from officials with government agencies, international agencies, and non-governmental organizations.
