Design of a Combined Filter to Reduce the Attenuation Decline in Magnitude Response
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.
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.
