Abstract:
A computerized fetal ECG(FECG)system is presented,w hi ch is composed of two components.One is the data collection device with a PIC m icrocomputer as the main hardware,which has low power consumption and gets power supply through serial port.The other is a software platform based on PC,which i s built through LabView6.1,a graphic programming language.Plenty of modules prov ided by LabView6.1utilized,it is efficient to develop the software platform.In particular,the implementation of the matched filtering algorithms is introduced ,which is the core of the software platform.A new method of updating templates o f matched filter is described.
