We examine the use of different high-level filter architectures (cascade, lattice, and parallel). We discuss their advantages and disadvantages, and we present simulation results and filter-tolerance tests. This information serves as a useful comparative analysis in the selection of a high-level filter architecture for a particular problem. The sensitivity to nonlinearity is also evaluated as resonance-enhanced power in the feedback path. For narrowband band-pass responses, cascade architectures appear to be more tolerant to filter parameter variations than lattice architectures and are substantially more efficient than parallel architectures.
