Discussion of Different Teaching Methods of Overlap Content in “Signal and System” and “Digital Signal Processing”

Digital Signal Processing” and “Signal and System” are both fundamental courses for EE study. The contents of “Digital Signal Processing” are based on concepts and theories of “Signal and System”, so it is always arranged following “Signal and System”, but there are overlap contents in the both courses, such as analyzing of discrete signal and system, so the problem is how long time should we use on these contents in “Digital Signal Processing” teaching. To find solution, we implemented an experiment in three grades students and found the optimal time for teaching these overlap contents.
