    This study introduces a microprocessor system to detect and quantify sharp electroencephalogram (EEG) waveforms. The automated system accurately measures waveform characteristics, mimicking human analysis for improved efficiency.

    Area of Science:

    • Neuroscience and Biomedical Engineering
    • Signal Processing

    Background:

    • Accurate detection and quantification of sharp electroencephalogram (EEG) waveforms are crucial for diagnosing neurological conditions.
    • Manual analysis of EEG data is time-consuming and prone to inter-observer variability.
    • Automated methods are needed to improve the efficiency and objectivity of EEG analysis.

    Purpose of the Study:

    • To describe a novel microprocessor-based system for the automated detection and quantification of sharp EEG waveforms.
    • To evaluate the system's performance in approximating human analysis and providing precise waveform measurements.

    Main Methods:

    • A hierarchical approach was employed, starting with transient detection using a second-derivative measure of curvature.
    • Subsequent pattern-recognition and artifact-rejection routines were implemented based on specific waveform parameters.
