Computation of Model Curves for Central Frequency Sounding by Means of Digital Linear Filter
MetadataShow full item record
Starting with basic equations for CFS response, the computational approach is developed. A linear relationship exists between the magnetic number and the kernel function involved in the integral expression. The normalized vertical magnetic field is determined by subjecting sample values of the kernel function to a digital linear filter. With the help of given filter coefficients, response curves for homogeneous and two-layer Earth models are computed, presented and qualitatively analysed.
