摘要
本文从模拟地震振动台试验系统的实际应用出发，研究了多级多速率数字滤波在抽样率转换和低通滤波中的作用和设计以及ＤＳＰ的实现；对其实现过程中的多路开关初始位置的设置、多通过之间时差的处理等问题予以讨论。
This paper studies the design and realization with DSP of multistage multirate digital filtering which is used to conversion of sample rate & lowpass in the shaking table test of Earthquake Simulation, and discusses the setting of the initial commutator position and method to eliminate the skew between the channels.
