This section contains two courses on signals and systems, based primarily on the book Structure and Intepretation of Signals and Systems, by Edward Lee and Pravin Varaiya.

• The first course was designed as a very gentle introduction to the field, using the notation and concepts described in the book. It has a carefully-structured delivery, and requires extensive support in the form of tutorials and Matlab exercises. It is suitable as a sophomore-year course; in some institutions it could possibly even be done as a freshman course.
  
  
• The second course is a follow-up course that aims to deepen the students' theoretical knowledge and make them proficient at analyzing, simulating, and implementing signal processing systems. It relies much more on self-directed learning, and assumes that students have the ability to tackle exercises and problems as needed in order to gain the necessary understanding.

(Modules A through E comprise the first course; modules F through J the second.) Instructors who wish to use this material in a class are welcome to have access to the subversion repository containing them. Apart from allowing you to contribute back to the materials, you will also get access to material that I don't really want posted publically, such as past exams and reference solutions.

I'd love to hear from you if you're interested in using this material in a class. Execute this Matlab code to get my email address:

function email=johnsemail()
  name = strvcat('john','reekie');
  host = strvcat('uts','edu','au');
  email = deblank(name(1,:));
  for i=2:size(name:1)
    email = email '.' deblank(name(i,:))];
  end
  email = [email '@' deblank(host(1,:))];
  for i=2:size(host:1)
    email = email '.' deblank(host(i,:))];
  end
