The active filter acts as an infinite impedance to the external for the fundamental frequency and as a low resistor for harmonic frequencies.

对外电路而言，在基波频率下有源滤波器被控制为无限大阻抗，在谐波频率下被控制为小电阻。

With this system, a study has been made on the correlation between respiratory impedance and dynamic compliance of rabbit, and oscillatory frequency.

利用这一系统，研究了家兔的肺阻抗和动态顺应性与振荡频率的依赖关系。

Power lines are extremely hostile places for data signals, with high levels of electronic noise and an obstacle course of transformers, surge arrestors and splices that create a huge impedance to the free flow of high-frequency signals.
