Popis:	Wave transmission through periodic and periodic layered structures is studied and the `average transmissivity' for an incident beam with a bounded uniform spectrum is defined. Both positive and negative -function and rectangular potentials are analysed. The phenomenon of the `resonant transmission', where the wave number is in a permitted band of the central layer and in a forbidden band of the side layers of a three-layer system, is also treated. Consequences of the results, applied to the construction of band pass filters, are discussed.
