Signals are everywhere! Audio, images, movies, cellphones, computers, medical imaging, and more! In this talk we will discuss signals and the some of the mathematical methods used to process, transform, and interpret signals. We will focus on orthogonal basis and frame methods for signal processing. The orthogonal basis methods are well established and even appear in our curriculum. However, there have been  many recent advance in frame methods, especially in constructing redundant methods to compensate for signal loss and corruption.  The talk should be accessible to students who have completed the Calculus and DE sequence.  One of the reasons for giving this talk is to interest students in a thesis or math project in this topic area in the next couple of years.  So, I particularly invite sophomore and junior math majors and double majors to attend.
