Outline (in English)

In traditional signal processing, the natural variables time (t) or frequency (f) have been used exclusively and independently each other in their methods, techniques, and algorithms. Recently, a set of signal processing methods which is called “Time-Frequency Signal Processing (TFSP) in which either time t and frequency f are used simultaneously has become a standard signal processing technology with applications found in all traditional areas of signal processing and beyond.
【Course outline】
This course introduces the essential concepts on which the field of TFSP is built.
【Learning objectives】
The objectives of this course are to master the following items. (1) Describe basic signal representations in time domain and frequency domain. (2) Understand the terminology used in time-frequency representation. (3) Understand and implement Fourier analysis and spectrograms. (4) Understand and implement Wigner and Wigner-Ville distributions. (5) Understand Wavelet transforms, and implement continuous and discrete orthogonal Wavelet transforms.
【Learning activities outside of classroom】
Exercises using Python (or MATLAB/Octave) will be conducted on a computer to deepen the understanding of time-frequency analysis theory. A brief explanation of how to use Python will be given during class time, but students are expected to study the details on their own. Actual data analysis may also be done outside of class time as homework.
【Grading criteria/Policy】
Computer-based exercises will be conducted to enhance the students' understanding of the theory of signal analysis, especially the time-frequency analysis method, which they have learned during the class. Grading will be decided based on those reports of the exercises.
