X1 probe: no attenuation, input impedance follow that of scope input impedance (usually 1 Mohm). This type of probe is seldom used because of heavy loading effect on circuit under test.
X1探头﹕没有衰减﹐输入阻抗跟示波器输入阻抗一样(通常是1兆欧)。由于对测试电路有很大的负载影响﹐所以很少使用这种探头。
Computer simulations also validate that the good attenuation effect can be obtained in the active self noise canceler if the signal component in the reference input is small.
同时，计算机仿真说明，只要参考输入中信号分量较少，自噪声有源抵消器仍然可以达到较好的降噪效果。
If a proper non - linear change of the instantaneous frequency is realized, we can get a frequency spectrum whose input is the mean of the reciprocals of bed attenuation coefficients.
如果把瞬时频率作适当的非线性变化，就可以得到一个以地层衰减率的倒数的平均值为输入的频谱。
Moreover, L_2 gain is used to analyze the disturbance attenuation ability of systems subject to both input constraints and exogenous disturbance.
在外部干扰和输入约束同时存在时，采用L_2增益方法分析了系统的干扰抑制能力。
Results show that the mezzanine foam has a very good blast-wave attenuation function, and this attenuation function increases with the input pressure force increase.
结果表明：泡沫夹层对爆炸冲击波具有很好的衰减作用，且这种衰减作用随输入压力的增大而增大。
