General Introduction
This course focuses on the core concepts of “convolution” and “Fourier transform,” using “time-domain and frequency-domain” transformations as analysis methods.
It uses the “three main transforms” as mathematical tools and serves as a crucial bridge course, providing the core theoretical foundation and methodology for modern information technology.

This Course is for
1. Helping trainees master the core concepts and principles of signal decomposition and combination, as well as linear time-invariant systems.
2. Enabling trainees to learn time-frequency transformations and establish mathematical models for linear time-invariant systems.
3. Helping trainees understand the basics of engineering applications, such as signal sampling and modulation or demodulation.
