Abstract :
A straightforward approach to the derivation of digital spectral transformations from the analog reactance functions is presented. This method is an alternative scheme and an extension to the problem of spectral transformations for one- and two-dimensional digital filters. To obtain two-dimensional frequency-band transformations for a given reference digital filter, the procedure uses the concept of bivariate reactance functions.<>
