Abstract
The circuit,which has high accuracy,multi-channel and strong real-time operational performance,and takes ARM kernel S3C2440 as its processor,and 24-bit ADS1256 chip with the analog switch as its A/D conversion and signal input channel,was designed for a seismic data acquisition system. The bridge low-pass filtering input of data effectively inhibits the common mode signal through long wire and greatly improves the ability of the whole circuit resistance against electromagnetic in-terference,by which the characteristics of high precision,high quality,low consumption and portability were realized for the seismic data acquisition system.关键词
