Abstract :
A systematic method for the realization of complex digital filters based on the concept of the generalized-immittance converter is presented. The method is simple to apply and can be used to realize arbitrary one-dimensional and multidimensional complex digital filters. The method is then used to realize a fourth-order Chebyshev filter, and the sensitivity performance of the filter is compared with that of other known low-sensitivity structures.
