Abstract
This paper proposes an efficient design method of three-dimensional digital filters by the outer product expansion. Specifications of three-dimensional digital filters are decomposed into specifications of one-dimensional digital filters by the outer product expansion, and then each specification of one-dimensional digital filters is designed. This procedure can be applied to both space- and frequency-domain specifications. Diagonal symmetries of three-dimensional digital filters can be exploited to reduce computations in the design procedure.
