| Outline of Final Research Achievements |
The goal of our research is developing the efficient method to observe and control spatio-temporal distributions of physical quantities. In order to realize the object, we have proposed a multidimensional delta-sigma modulation to the signal processing of the sensor and actuator arrays.
As a result of the research, we have presented a design method to implement stable high-order multidimensional delta-sigma modulation. We expect the technique will expand the application area where simultaneous observations or controls are needed for temporal and spatial distributed physical quantities such as vibration, sound and radio waves, etc.
