MODULE DETAILS Module 8: Digital Circuit Design   Nominal duration: 4 weeks (32 hours total time commitment)   This time commitment includes the preparation reading, attendance at each webinar (1 hour plus 15-30 minutes for discussion), and the time necessary to complete the assignments and further study. MODULE PURPOSE The subject area of electronics forms one of the main pillars supporting Mechatronics systems. The electronics discipline can further be subdivided into two sub-disciplines, viz. analog and digital electronics. In this module the operation and application of digital components is investigated. This includes SSI devices such as logic gates, and MSI devices such as flip-flops, shift registers and counters. The study of these devices is not be limited to theory; delegates will design and simulate circuits with computer software, and then physically (optionally) build and test them in order to verify the design and simulation.
