DFS—V数字地震仪低通滤波器中双T网络的分析

ANALYSIS OF TWIN-T NETWORKS OF ANTI-ALIAS FILTER IN DFS-V SEISMOGRAPH

The twin-T networks of anti-alias filter in DFS-V seismograph are analyzed in this paper. It is pointed out that the twin-T networks of anti-alias filter in DFS-V are different from the standard balanced ones. And the advantage of the former’s design has been described.
