The proposed architecture adopt recursive pyramid algorithm(RPA)instead of the classical pyramid algorithm(PA), only one low-passfilterandhigh-pass filter are required to compute all levels.
The highpassandlow pass and ellipse-filter are realized by the medium of the MAX264 s programming.
然后利用单片机对MAX264编程,实现低通、高通及椭圆滤波器。

The DCZ4 vibration measuring instrument is an advanced multi-function andlow-frequency instrument for lowpassfilter, high pass filter and double integration.
