【Abstract】 The method of Computer Aided Design of electrocircuit was discussed.The math modeling and imitate by computer of the filter have been done.Under the condition of the parameter of electro circuit was changeless,the filter’ frequency response and the infection which was done by resistance and capacitance were studied.The result shows that along with the frequency hoist,the output waves of filter was fall,and the more great the resistance and capacitance’value,the more great the undue peak value and the better effect of filter would be.The emulate result was match case with account under theory of voltage transfer function.更多还原
