1. Description of signals Signals are generally represented by functions of one or more independent variables, such as voltage signals are generally functions of time. In this course, the terms \"signal\" and \"function\" are often used interchangeably; signals can also be represented by waveforms; for discrete signals, they can sometimes be represented in the form of a table; signals can also be described from other aspects, such as using its spectrum, Laplace transform, its z transform, etc. These contents are the basic contents of signal analysis; mastering the correspondence between functions and waveforms is a basic skill for learning signals and systems. 2. Classification of signals There are many ways to classify signals, and signals can be classified from different angles. Classification by actual use: TV signals, radar signals, control signals, communication signals, broadcast signals... Classification by time characteristics
