Abstract
Abstract A configurable analog and digital array is realized in a hierarchical structure on at least two levels. It comprises at least two first-order matrix arrays, each of said matrix arrays including a plurality of basic elements which are arranged in rows and/or columns and at least part of which are analog basic elements, and a first switch matrix for controllably interconnecting the signal inputs and the signal outputs of the basic elements and for connecting said basic elements to matrix inputs and matrix outputs, as well as at least one second-order matrix array having a second switch matrix for controllably interconnecting the matrix inputs and the matrix outputs of the first-order matrix arrays and for controllably connecting said matrix arrays to array inputs and array outputs.
