Design of a filter-bank by the wave digital filter technique an approach for the Chebishev bank-filter by the wave digital filter technique

This paper presents a simple procedure for design of the filter-bank with Wave digital filter (WDF). The filter-bank is constructed using Chebyshev and Inverse Chebyshev filters. Wave digital filters are derived from LC filters and consist of cascade connections of serial and parallel adapters. These adapters contains the necessary adders, multipliers and inverters. A great advantage of this procedure is that the filters in the wave digital filter-bank synthesis are obtained from the wave digital filter-bank analysis only by changing some signs in the end of delay elements.
