ABSTRACT:
A multiplexing device is provided which is used in listening channels for a panoramic sonar system. An arrangement of a multiplexer, a demultiplexer and a storage register provide a circular permutation of hydrophone inputs to a time delay network. The resultant rotation of these inputs, as provided by appropriate gating circuits, is used forming the desired listening channels for the sonar system.
