Wednesday February 9, 2011 (Week 5) - See Course Schedule.
Today I presented a couple of examples of DT Fourier series coefficient computations. The examples I chose are very similar to the ones in the homework. You should remember that there are two different methods for computing the DT Fourier series coefficients. One is very quick but only applies when you can figure out a way to directly write the function as a linear combination of exponentials. It also requires a good understanding of the properties of harmonically related exponentials. The other one is a bit more computationally intensive but, in a way, more straightforward: you don't have to think much, you just plus into the formulas and simplify.
Action items before the next lecture:
- Read Sections 3.3, 3.7 in the book.
- Keep working on the fourth homework.
- Practice computing DT Fourier series: Two practice problems are posted already. Let me know if you need more.
