并采用高集成度的开关电容滤波器，系统的采样频率和反混迭滤波器的截止频率可在一定范围内任意给定。
Using the highly-integrated Switch-Capacitor filter, the sampling rate and the cut-off frequency of the anti-alias filter can be arbitrarily selected within some range.
文中以DFS - V数字仪为例，对高、低截频滤波器的截止频率进行了具体地设计计算，其目的在于进一步提高现有数字地震仪的性能和适应能力。
For example, new cut-off frequencies for low and high cut-off filters in DFS-V data acquisition system were designed in or - der to improve...
