EE1.el3  Electronics 3: mechanics & acoustics (EEE1023)

Welcome!

This is the EE1.el3 Electronics 3 website where you'll find information about lectures, books, exercises, exam papers, links and other sources of help.

As in your timetables, the lectures are on Thursdays at 12pm in 01-AC-01 and Fridays at 9am in 04-AZ-01. There is also an occasional slot used on Tuesdays at 12pm in LT-F. The lecturers are Prof Karen Kirkby (KK, orange) and Dr Philip Jackson (PJ, yellow), who is the module coordinator.

This module homepage also has a mirror under my personal homepage.

There are some exercises here for you to do in your own time, so you can make sure you are digesting and understanding the material from the lectures.

There is information about past exam papers relevant for this module.
