Lecture 2 Blog, ECE438 Fall 2011, Prof. Boutin
Wednesday August 24, 2011 (Week 1) - See Course Outline.
In the second lecture, I explained how to transition from the continuous-time Fourier transform in terms of $ \omega $, which you have seen in ECE301, to the continuous-time Fourier transform in terms of f. Some subtleties regarding the rescaling of the Dirac delta were observed. The "rep" and "comb" functions were introduced, and in the next lecture, we shall compute their Fourier transforms.
Action items:
- Solve the following two practice problems and share your solution for feedback
- Begin working on the first homework was announced. It is due next Wednesday (in class).
Relevant Rhea pages previously created by students:
- About the CTFT in terms of f and its properties
- About scaling of the Dirac Delta
- About the Rep and Comb function
- Summary of CT and DT Fourier transforms
Do you see any mistake in these pages? Do you have questions? Feel free to write comments directly on these pages. But if you wish them to modify them completely, please make a copy of the source code on a new page and make your modifications there. In other words: do not completely destroy other people's work.
