ABSTRACT
This paper introduces the research and realization of an adaptive fetal electrocardiograph (FECG). We have developed an embedded system which takes the digital signal processor chip TMS320LF2407A as the core. According to the principle of adaptive noise cancelling(ANC), the ANC software algorithm is studied and realized to extract the FECG by non-invasive means, then the embedded system sends the data to the computer through the communication interface for real-time display, analysis and recording of the processing results. The experiments indicate that the design is reasonable and the instrument owns a good performance.
