双二阶滤波器 meaning in English

biquadratic filter

Continuous - time analog filter is the only method when processing high frequency signal ( usually above 1mhz ) in low power consumption . it has been widely used in the area of communication , electronic measurement , instruments , autocontrol , etc . it ’ s especially used in digital and analog mixed signal processing and communication integrated circuit . current - mode filter becomes the new research direction in the world , as it ’ s high speed , low power consumption and simple configuration
提出了基于ota的多功能电流模式双二阶滤波器,基于ota的八阶切比雪夫滤波器,用模拟lc梯形电路法设计椭圆低通滤波器时,在传统的状态变量选取方法的基础上,用改进后的状态变量选取方法得到了( k + 1 )阶椭圆函数低通滤波器的简化信号流图,实现了简化的基于ota的椭圆低通滤波器电路。
