SURFACE ACOUSTIC WAVE COMPONENT WHICH CAN BE INTERROGATED BYRADIO AND HAS AN OPTIMUM CODE SIZE

摘要

A coding scheme is specified which, compared to the prior art and with the system having a structure resolution (.DELTA.) of the same magnitude, allows an enlarged code size for the same number of code elements, and/or by means of which fewer code elements are required per code for a predetermined code size. The code elements (reflectors 21 or resonators 220) are arranged with basic values in a matrix (30) defined in a novel manner, with this matrix having a finer subdivision (.delta.) of the basic values (130) than the subdivision corresponding to the structure resolution (.DELTA.). Further development with mean-value formations.
