Viewed from the power line side the lisn is a low pass filter that isolates disturbance from the power line by up to 40db 从电源输入一边看， lisn是一个低通滤波器，它隔离市电干扰高达40db 。
The following is a partial list of lc lowpass filters and their specifications that we have produced , arranged by center frequency 以下为生产过的lc低通滤波器部分产品规格（按截止频率排序） 。
Long - term interest rates could even go up if bond markets start to distrust the feds commitment to maintain a low rate of inflation 如果债券市场开始质疑美联储维持低通胀率的承诺，长期利率可能进一步走高。
By emulation , some technique problems have been figured out : the modulation arithmetic , the control mode and the design of low - pass filter 通过仿真计算，解决了调制算法、控制方式及低通滤波设计等技术问题。
Photoelectric detecting circuit is constituted of four parts , i / v conversion , lock - in amplifier , low - pass filter and operation 光电检测电路由四部分组成,分别是i / v转换环节、锁相放大环节、低通滤波环节、运算环节。
This is the rate consistent with both a sustainable current - account balance and internal balance ( ie , full employment with low inflation ) 这是一种与可持续的经常账户平衡和内部平衡（低通胀下的充分就业）相符合的比率。
3 . based on the low - pass filter coefficients of daubechies 4 wavelet , we present another multiscale recursive data fusion estimation algorithm 3 .基于daubechies4小波的低通滤波系数，发展了一种新的多尺度数据融合估计算法
Owing to high frequence , city power peak and pou can be removed by low band - pass filter that we design in the fourth chart 对于市电的尖峰和浪涌噪声，由于其属于高频成份，在本文第五章，我们设计了低通滤波器来滤波，消除其影响。 。
As a consequence of this simulation , however , the cut - off frequency of the resulting low - pass is 70 . 7 per cent of the specified bandwidth , and not 50 per cent 然而这种模拟的结果是：最终的低通截止频率为特定带宽的70 . 7 % ，而非50 % 。
