Abstract

A major contribution to the interpretation of electrical measurements was made with the application of digital linear filtering introduced by Ghosh (1970, 1971a, b). This rendered the computations easy and fast. In a recent publication, I showed (Das, 1982) that the filters for computing responses for any electrode or coil configurations employed in electrical methods could be derived easily from stored basic spectra of the two filter functions, namely, {exp (x − y)J0[exp (x − y)]} and {exp (x − y)J1[exp (x − y)]}. One has to multiply the stored spectra by simple factors to arrive at the required spectra. I show here that a simple mathematical manipulation transforms a J0 domain integral into its corresponding J1 domain integral, thereby leading to the use of a single J1 filter for a variety of computations in electrical methods.
