Identifier: http://hdl.handle.net/1959.13/919679
Description: Errors-in-Variables systems have been extensively studied in the literature. We study the impact of sampling on a continuous-time errors-in-variables problem. In particular, we study some approximatio... More

Identifier: http://hdl.handle.net/1959.13/928893
Description: Both direct and indirect methods exist for identifying continuous-time linear systems. A direct method estimates continuous-time input and output signals from their samples and then use them to obtain... More

Identifier: uon:6042
Description: Most real world systems operate in continuous time. However, to store, analyze or transmit data from such systems the signals must first be sampled. Consequently there has been on-going interest in sa... More
