The Analog & Digital Communications Systems Lab Experiments and Courseware available here engages students with LabVIEW-based exercises and experiments that cover both theory and practice. The material development was supervised by American University of Beirut (AUB) professors Dr. Zaher Dawy (zd03@aub.edu.lb) and Dr. Ernst Huijer (eh09@aub.edu.lb) for the EECE 442L Communications Laboratory, a junior-/senior- level lab course in the AUB Electrical and Computer Engineering Department.
