| Abstract: | In this paper,a three-pole active filter is designed adopting the subsystem's cascading and normalization.The transfer function of the system is calculated and the process of selecting the circuit parameters is presented in details in this paper.The circuit is simulated.It's proved with experiment that three-pole active filter with excellent performance can be acquired by adjusting the value of resistance and capacitance. |
