Presented here is a new advanced fetal ECG and heart rate monitoring system. A lot of improvement has been made to resolve the problem with traditional instruments, for which it is difficult to extract faint FECG.In respect of fetal ECG signal extraction and processing,the new system solved the problem in detecting faint FFCG, which are difficult to obtain with matched filtering method. In respect of system hardware,the isolated amplifier is optimized and a new fetal monitoring system based on 486PC was des...
