Area of Science:

  • Biomedical Engineering
  • Signal Processing
  • Medical Instrumentation

Context:

  • Fetal electrocardiography (FECG) is crucial for monitoring fetal well-being.
  • Non-invasive FECG signal acquisition presents challenges due to maternal and environmental noise.
  • Existing methods may lack the processing power or real-time capabilities for comprehensive analysis.

Purpose:

  • To introduce a new microcomputerized Fetal Electrocardiograph (FECG) system.
  • To detail the two-grade configuration, including front-end and back-end processing.
  • To demonstrate the efficacy of Adaptive Noise Cancelling (ANC) for FECG extraction.

Summary:

  • A novel two-grade microcomputerized Fetal Electrocardiograph (FECG) system is presented.
  • The front-end utilizes a Digital Signal Processor (DSP) TMS32010 and an Adaptive Noise Cancelling (ANC) algorithm for non-invasive FECG extraction.
