| Abstract: | The paper presents a fetal electrocardiogram system based on MSP430 and USB interface.The hardware and software of the system are also introduced.In the system,it synchronously samples MECG signal and FECG signal by using ultralow-power micro-controller MSP430F149 of TI,and then the sample results are uploaded to PC by USB interface.The results will be stored,processed and showed by software on the PC.This design of FECG is high in quality,low in cost and easy in use. |
