Digital Waveguide Mesh

In §H.10, the theory of multiport scattering was derived, i.e., the reflections and transmissions that occur when digital waveguides having wave impedances are connected together. It was noted that when is a power of two, there are no multiplies in the scattering relations Eq.(H.91), and that this fact has been used to build multiply-free reverberators and other structures using digital waveguide meshes [439,526,146,401,529,530,402,403,405,55,205,329,328,330,430,32].
