摘要
在分析压电式传感器的信号适调特征基础上,介绍了新研制的集截止频率可程控的抗混叠滤波器与电荷放大器模块于一体的新型多功能电荷放大器适调模块和集截止频率可程控的抗混叠滤波器与恒流源于一体的新型多功能ICP传感适调模块的原理、特点与主要技术指标。
Based on analyses the signal conditioning features of piezoelectric sensor, introduced principle, feature and main specifications on the newly developed muhifunction charge amplifier adjustable module which integrate cut-off frequency programma- ble controller anti-aliasing filter and charge amplifier module, and on the newly developed multifunetion ICP sensor adjustable module which integrate cut-off frequency programmable controller anti-aliasing filter and constant-current source supply.
