original question: what Patent has an Associated Invention that is associated with the patent [Multidimensional digital waveguide signal synthesis system and method (tetrahedral extension)]?
answer: multidimensional digital waveguide signal synthesis system and method
answer type: Patent.
auxiliary information: This variation on the Digital Waveguide Mesh design comprises bidirectional unit delays and 4-way no-multiply junction computations to model wave propagation in 3D space or homogenous solids.  It is based on an equivalence under certain conditions of modeling of transmission line scattering as digital waveguides and partial finite difference schemes for 3d wave propagation.
