Digital Waveguide Mesh

In §G.10, the theory of multiport scattering was derived, i.e., the reflections and transmissions that occur when $N$ digital waveguides having wave impedances $R_i$ are connected together. It was noted that when $N$ is a power of two, there are no multiplies in the scattering relations Eq.$\,$(G.91), and that this fact has been used to build multiply-free reverberators and other structures using digital waveguide meshes [434,522,144,396,525,526,397,398,400,55,203,326,325,327,425,33].
