1·The amplitude of signal filtered declined light not liked that the center position of energy spectrum moved to the left obviously used the highpass filter to filter.
滤波后信号幅度的衰减比较小，没有像高通数字滤波器滤波后能谱峰的中心位置有明显的向左偏移现象。
2·Higher Highpass resonance Q indicates a lower rate of energy loss i. e. the oscillations die out more slowly.
较高的高通共振质量表示一个能量损失率较低，振动消失更慢。
3·Based on this configuration, a first order lowpass or highpass filters and a second order lowpass or highpass filter can be constructed.
由该模型电路可产生一阶低通、一阶高通及二阶低通、二阶带通滤波器。
4·The important feature of the proposed si circuit is that it can simultaneously obtain lowpass, bandpass and highpass filter outputs, in a single building block.
该电路的一个重要特征是：它在单一积木块上能同时获得低通、带通和高通滤波功能。
