测试测量 基于MASON公式的多功能二阶通用滤波器设计

基于通用集成运算放大器，利用MASON公式设计了一个多功能二阶通用滤波器，能同时或分别实现低通、高通和带通滤波，也能设计成一个正交振荡器。电路的极点频率和品质因数能够独立、精确地调节。电路使用4个集成运放、2个电容和11个电阻，所有集成运放的反相端虚地。利用计算机仿真电路的通用滤波功能、极点频率和品质因数的 ...

模拟电子 Active Filters

Power conversion by virtue of its basic role produces harmonics due to theslicing of either voltages or currents. To a large extent the pollution in theutility supply and the deterioration of the power quality has been generatedor created by non-linear converters. It is therefore ironic that power c ...
