| Abstract: | For photoelectric weak signal detection,a Sigma-Delta AD converter AD7706 and an AVR MCU ATmega8515 are used to design a high-precision data acquisition system which is applicable to low-frequency signal measurement.A Sigma-Delta AD converter ADC16471,an AVR MCU ATmega8515,a C51 MCU C8051F020 and an Ethernet controller chip RTL8019AS are used to design a high-precision data acquisition system which is applicable to a high-precision linear CCD.Both data acquisition systems are collected for the experimental study and performance analysis. |
