TOPIC Introduction to discrete time systems 
AREA Communications & Networks  
SPEAKER Dr Charles Lim, Oak Ridge National Laboratory, United States of America  
DATE 28 March 2017, Tuesday 
TIME 1.30pm to 2.30pm  
VENUE E5-03-20, Engineering Block E5, Faculty of Engineering, NUS  
FEES No Charge 

SYNOPSIS
Digital signal processing is necessary for improving the reliability and accuracy of digital communications. The lecture will focus on linear time-invariant (LTI) systems for one-dimensional signals, touching on system properties (linearity, stability, etc) and characterization techniques (convolution sum and difference equations). 

ABOUT THE SPEAKER
Dr. Lim got his B.Sc. (Hons) in Physics from the National University of Singapore, and his Ph.D. in Quantum Communication from the University of Geneva, Switzerland (under the supervision of Nicolas Gisin and Hugo Zbinden). Since 2015, he has been working as a research associate in the Computational Sciences and Engineering Division at the Oak Ridge National Laboratory of the United States. Dr. Lim’s research is broadly focused on the theory of quantum communication and information theory. A feature of his research is the security of practical quantum cryptosystems. Notably, his theoretical contributions in this area has led to the world’s longest distance quantum key distribution experiment (Nature Photonics 9, 163, 2015).
