Bode Plot Analysis and Exam Schedule for EE4201 - July 2023

This announcement outlines important details for EE4201, including the last homework on Bode plots and the submission deadlines for Lab#3 and Lab#4 reports. It also provides the schedule for upcoming tests: Exam IV will be held on July 24 as an open-book exam, and the final exam will follow on July 29, based on the content of the previous four tests. Additionally, it emphasizes the key concepts of Nyquist and Bode diagrams, including their mathematical backgrounds, system responses, and control design principles.
