# Lecture 18 Blog, ECE301 Spring 2011, Prof. Boutin

Monday February 21, 2011 (Week 7) - See Course Schedule.

Today we obtained the formula for the Fourier transform of a periodic signal. We found that we cannot compute the Fourier transform of such signals using the integral formula. However, we were able to guess the answer and give a mathematical proof that our guess is correct.

We finished the lecture by discussing a few properties of the continuous-time Fourier transform.

## Action items before the next lecture:

- Read Sections 4.4, 4.5, 4.7 in the book.
- Solve the following practice problem on CT Fourier transform.
