Foureir Transform
 YAMAZAWA Hiroshi HIROSE Sampei
Course description
Images and sound can be thought of as superpositions of signals (waves), which can be used for compression and noise reduction. The basis for this is the fact that functions can be decomposed into waves, and this is called Fourier analysis after Fourier, who studied this.
In this class, students learn the main tools in Fourier analysis: Fourier series, Fourier transform, wavelet transform, and their applications.
Purpose of class
The purpose of this class is to understand the concepts of Fourier series, Fourier transform, and wavelet transform, and to be able to perform calculations. In addition, students understand how they are used in signal processing and other applications.
Goals and objectives
1. To be able to understand the definition of Fourier series expansion and be able to calculate it.
2. To be able to understand the definition of wavelet series expansion and be able to calculate it.
3. To be able to understand the definition of Fourier transform and be able to perform basic calculations.
4. To be able to understand the definition of wavelet transform and be able to perform basic calculations.
5. To be able to understand the following applications of Fourier analysis.
*Differential equation solving using Fourier transform
*Definition of multiresolution representation and its calculation method
