Method and apparatus for time-division transmission of the received signals electroacoustic transducer

摘要

In a method for time-division transmission of the received signals electroacoustic transducer (11) at different transducer locations (13) of a spatially extended receiving arrangement (10) are placed, to a signal processing unit (12) at each be transducer location (13) by means of an electronic module (20) the received signals are digitized, and the digitized signals in the grid of a synchronizing a clock pulse to the signal processing unit (12), leading to the data line (14, 15, 16) is applied. In order to achieve a high data rate in the case of undisturbed data transmission, the electronic modules (20) with respect to the inherent - both for by the grid predetermined aufschaltzeitpunkten is measured and to the transducer locations (13) by individual time delay of the ends of the switching signals to be compensated (fig. 1).
