Novel wave digital equivalents of passive elements

The wave digital equivalent of passive elements using wave theory and bilinear transform is formulated in yesteryear, but the bilinear transform produces large distortion in the mid and high frequency range. In this paper, a novel wave digital equivalents of analog passive elements are developed. Instead of bilinear transform, two different transforms are used for analog to digital (A/D) conversion in order to overcome the limitation of the aforementioned transform. The comparison of transforms along with the resultant wave digital equivalents of passive elements using these transforms and wave theory is introduced. In this paper, it is also considered that practically, analog elements are not ideal, but leaky. So, wave digital equivalents of leaky analog elements are also proposed.
