Catalogue Description: MATH 414. Fourier Series & Wavelets. Fourier series and wavelets with applications to data compression and signal processing. Prerequisite: MATH 323 or MATH 304 or MATH 311

Required Text: A First Course in Wavelets and Fourier Analysis, 2nd Edition, by Boggess & Narcowich

Time & Place: MWF 12:40-1:30 pm, BLOC 164

Programming language: Experience with MATLAB would be very helpful.

Grading System & Tests: Your grade will be based on a project, homework, two in-class tests ( Wednesday, February 26 & Wednesday, April 8). and an online final exam (Friday, May 1). The project will count for 20% of your grade, homework for 20%, each in-class test for 20%, and the final exam for 20%. Your letter grade will be assigned this way: 90-100%, A; 80-89%, B; 70-79%, C; 60-69%, D; 59% or less, F.

Make-up Policy: I will give make-ups (or satisfactory equivalents) only in cases authorized under TAMU Regulations. In borderline cases, I will decide whether or not the excuse is authorized. Also, if you miss a test, contact me as soon as possible.

Homework and Projects: You may consult with each other on homework problem sets, BUT only submit work which is in your own words AND be sure to cite any sources of help (either texts or people). Be aware that usually only some of the problems from an assignment will be graded. Late homework will not be accepted. Information concerning projects may be found on at this webpage: Project Information.
