We introduce the notion of extended sensors and we show that the observation error decreases when the support of a sensor is widened. We also show that the observation error decreases when the number of sensors increases.}, type={artykuł}, title={Regional observation and sensors}, keywords={distributed parameter systems, sensors, observability, observation error}, }
