ABSTRACT:
Waves such as radio-waves, sound waves, or electric current waves are used for communication among system units. Each system unit includes a reference oscillation generation apparatus which receives as input a sum of a sent wave and a received wave. An upper limit and a lower limit for input amplitude range is set in said reference oscillation generation apparatus. The apparatus modulates the output (sent wave) so as to meet the input amplitude range so that synchronization among a large number of distributed reference oscillation generation systems is attained. As a result, it becomes possible to eliminate phase differences among reference oscillation systems added to a large number of distributed system units and attain synchronization.
