Winter 2024: Communications  Electronics II

(this web page is at http://www.ece.ucsb.edu/Faculty/rodwell/Classes/ECE218b/ECE218b.htm)

Co: listed as ECE145b  (undergrad) and ECE218b (graduate)

 

DO NOT GO TO THE SCHEDULED LAB HOURS during the first week of classes. The laboratory/design content of the class is run on an independent basis. Design projects are assigned and a due date is given. Students work in the lab constructing and testing their designs, working in the lab at whatever time they find most suitable to work.

Tuesday: noon-1 PM: Lab

The office hours are for the TA to give you guidance with your projects and assignments. On weeks when lab projects are due, or even being worked on, the regular office hour times will not held, and the TA will instead be in the lab to guide you.. The TA will email the class to set up times for these.  They are also posted below, but check with the TA's emails if these two sets of records don't agree.

 

Please contact the TAs regarding HW solutions or grading.

Problem sets and design projects in the class use the Agilent ADS microwave IC design environment. Access to ADS can be either through accounts in the ECI lab, or via the microwave teaching lab on the 5th Floor of Harold Frank Hall. If you are member of a research group in the ECE dept, you may well also have access to ADS via your group's PCs or Workstations---ask your Professor.
