This paper deals with an extension of the wave‐digital filter structures introduced by Fettweis. A new structure is introduced, viz , the digital translation of the Jaumann structure. The Jaumann structure is a well‐known canonical realization of analogue, symmetric, grounded lossless two‐port networks. With this structure, transfer functions with complex transmission zeros can be obtained in a wave‐digital realization, which is not possible by means of a wave‐digital ladder filter. Two examples are given, one of which has been implemented using TTL digital integrated circuits showing excellent properties.
