We show how a suitable analog model enables us to derive directly the reflections and transmissions of a non‐uniform‐velocity layer. The results are compared with the exact solutions of the equations of propagation and with the solutions resulting from a sampling of the velocity distribution in the layer. The filters equivalent to propagation and sampling are deduced from these comparisons., UL https://www.earthdoc.org/content/journals/10.1111/j.1365-2478.1962.tb00002.x
