Signal and Systems 教師：潘欣泰
本課程目標 學生能熟悉離散及連續信號的時域和頻域的特性及運算 對線性非時變(LTI)系統的頻域分析及其輸入輸出信號的關係有基本的瞭解 學生在學習完本課程之後，應能熟悉傅立葉分析(Fourier analysis)及拉式轉換(Laplace Transform)及z-轉換(z transform)的相關技巧。

one dimensional (depend on single variable) — e.g. speech signal 1.1 What is a signal? A signal is formally defined as a function of one or more variables that conveys information on the nature of a physical phenomenon. one dimensional (depend on single variable) — e.g. speech signal Multidimensional (depend on two or more variable)– e.g. image singnal (two dimensional) 1.2 What is a system? A system is formally defined as an entity that manipulates one or more signals to accomplish a function, thereby yielding new signals. Figure 1.1 (p. 2) Block diagram representation of a system.
