    Area of Science:

    • Geophysics
    • Signal Processing

    Context:

    • Electro-rectification analysis (ERA) requires accurate potential measurements.
    • Disturbing frequencies in ERA potentials complicate data analysis.
    • Existing smoothing techniques may alter signal characteristics.

    Purpose:

    • To develop and present an optimized digital filter for smoothing ERA potentials.
    • To ensure the filter preserves the original form and amplitude of the potentials.
    • To compare the filter's efficiency against other smoothing methods.

    Summary:

    • A novel, optimized digital filter is proposed for ERA potential analysis.
    • This filter effectively eliminates disturbing frequencies without falsifying signal form or amplitude.
    • The performance of this optimized filter is evaluated against conventional smoothing techniques.

    Impact:

    • Enables more accurate and reliable analysis of ERA data.
    • Provides a tool for researchers to improve signal quality in geophysical studies.
    • Offers a potential advancement in signal processing for electro-rectification applications.
