Lecture 7 Blog, ECE301 Spring 2011, Prof. Boutin

Wednesday January 26, 2011 (Week 3) - See Course Schedule.

In lecture 7, we finished discussing the concept of time-invariance of a system (both for CT and DT), with two different definitions and some explicit examples. We also covered defined the concept of "linearity" for a system (giving three different definitions) and gave some explicit examples. Note that, of all the system's properties we have seen, linearity and time-invariance and the two most fundamental ones.

Action items before the next lecture:

• Read Sections 2.1 and 2.2 in the book.
• Solve the following practice problems on linearity and time invariance
  • Is the following system time-invariant?
  • Is the following system linear?
