Lecture 8 Blog, ECE301 Spring 2011, Prof. Boutin

Friday January 28, 2011 (Week 3) - See Course Schedule.

In lecture 8, we showed that the output of a DT LTI system can be written as a convolution sum between the input signal and the unit impulse response of the system. This was done using a sequence of three observations. Similarly, we showed that the output of a DT LTI system can be written as a convolution integral between the input signal and the unit impulse response of the system. We covered one example of a DT convolution. An example of a CT convolution will be given in the next lecture.

Action items before the next lecture:

• Read Section 2.3 in the book.
• Begin working on the third homework.
• Solve the following practice problem:
  • Compute the output of the following DT LTI system
