一种微形变量化检测系统研究

he design is applied to strain patches measuring the tiny form changes degree, and covering analog signals which strain patches collected to digital signal in order to analyze the data in computer. This thesis described in detail in the hardware structure and procedure that Single Chip Microcomputer controlled A/D converter TLC2543.The signal is handled by Non - recursive FIR filter.By experiment, This experiment proved that this equipment can accurately measure skin stretch and shrink degree, and provide the digital values to further analysis.
