Due to the existence of significant conduction losses, colloidal systems and other dielectric media frequently exhibit a typical low frequency dispersion in their dielectric spectra that goes unnoticed most of the time. The KK relations provide a way to transform data from " into ". As a result, we are able to compute conduction-free " spectra in which the l.f. dispersion will manifest itself unaltered. With a moving frame of logarithmically spaced data, this interconversion can be performed online. By applying symbolic differential operators and kernel matching, the coefficients of the conversion frames were found. Another method for conducting free data analysis is to use logarithmic derivatives and differences of'and '. These difference-based functions, which are essentially distribution function approximations, have the added benefit of enhancing the resolution power of dielectric studies. The rich relaxation structure of colloidal suspensions and the majority of other dielectric media makes a high resolution crucial. All-in-one modeling's advancement makes it easier to do high-resolution, free-form data analysis. Using this mathematical method, various data and numerous model functions can be fitted separately and then combined. Going completely around the KK conversion also turned out to be helpful. This resulted from the combination of approximation' and "information containing a complicated rational fractional power function. The dielectric modeling of a suspension with the complicated dipolar coefficient also proved to be a very effective use of the all-in-one minimization. It ensures that the electrode polarization will be securely corrected, enabling modeling using the differences' and "is able to focus on the actual colloidal relaxations.
