ABSTRACT:
Multi-dimensional digital filters have such a circuit structure that their transfer function corresponds to that of an antimetrical filter, and have a characteristic function that is a rational function of the squares of the equivalent complex frequencies. Multi-dimensional filters, wave digital filters as well, can thereby be realized having a closed attenuation behavior.
