摘　　要：以芯片MAX274为基础,设计出适合多频阵列感应的八通道带通滤波器,该滤波器不仅具有调试简单,维护方便,而且耐高温、噪声低、方便控制各道增益等优点。简要描述了设计要求、器件选择以及设计原理,重点阐述了带通滤波12/15通道的设计过程。通过多次室内高温试验以及现场测井试验表明,该带通滤波效果好,有较高的实用价值。Based on MAX274 chip, worked out is the ban＆pass filter with eight-channel for multifrequency array induction imaging loggings. This filter not only is simply debugging, easy maintenance, but also is against high temperature,low noise, and it is easy to control the gains and so on. Briefly described are the requirements of design, selection of device and work principles. Detailed is the design process of the 1215 channel. Many high temperature experiments indoor and logging tests on-site show that the band-pass filter has good effect and practical value.
