摘要
文中提出了改善有源低通滤波器截频特性的措施,将低通滤波器与带阻滤波器级联或与带通滤波器级联,其合成特性即为改善后的特性,文中又在理论上做了分析。并设计了电路,通过实验得到了满意结果。
In this paper,the measures which could improve the critical frequency characters of active low
-pass filter were put forward. By cascade connecting low-pass filter to band -exclusive-filter or to band
-pass-filter,the synthetic characters were improved. In addition,theoretical analysis was made in this paper. According to the ideas above,the cricuit was designed. Meanwhile,the satisfactory results were obtained by tests.
