先修科目或先備能力：
1. 工程數學(含線性代數、機率、常微分方程、複變函數)之基本觀念
Basic concepts in Engineering Mathematics (including Linear Algebra, Probability, Ordinary Differential
Equations, and Complex Variables)
2. 訊號與系統
Signals and Systems
課程概述與目標：
本課程介紹通訊信號傳輸之基礎理論與基本技術，是欲了解通訊工程者必備的基礎知識。課程內容
以介紹類比訊號傳輸方法及其效能分析為主，也以部分時間介紹數位通訊技術。雖然近年來，通訊
系統逐漸愈趨數位化，但本課程所介紹有關類比通訊的各種觀念及數學工具，其實仍是了解數位通
訊的重要基礎。本課程與後續的「數位通訊原理」形成內容連續之二學期課程；透過修習這兩門
課，可對通訊工程的基要有較完整的認識。但本課程在規劃上，並不假設學生會修習上述第二學期
課程。
This course introduces the basic theory and basic techniques for communication signal transmission. Such
material is the fundamental knowledge that anyone who intends to understand communication engineering must
possess. The course will concentrate on introducing analog signal transmission methods and associated
performance analysis, but will also spend a little time introducing digital communication technology. Although in
recent years, communication systems are more and more “digitalized,” the various concepts and mathematical
tools introduced in this course concerning analog communication nevertheless constitute important foundation for
understanding of digital communication. This course, together with its sequel “Principles of Digital
Communication,” form a two-semester curriculum with connected contents. A more complete understanding of
the fundamentals of communication engineering can be acquired by taking both these courses. But the
organization of the present course does not assume that students will also take the above second-semester course.
課程大綱
單元主題
內容綱要
Introduction
Introduces the concept of communication systems and gives some
examples.
Review of Signals and Systems
Reviews some concepts taught in the course Signals and Systems
that are relevant to the study of communication systems.
Linear Modulation
Introduces linear modulation methods and corresponding
demodulation methods. Emphasis is typically placed on introducing
double-sideband suppressed-carrier (DSBSC) modulation and
amplitude modulation (AM), single-sideband (SSB) and vestigialsideband (VSB) modulations, and mixing. Some time may be spent
on introducing analog quadrature amplitude modulation (QAM),
concept of multiplexing, concept of analog pulse modulation, and
noise effects on linear modulation methods.
Angle Modulation
Angle modulation usually refers to frequency modulation (FM) and
phase modulation (PM). This unit introduces angle modulation
methods and corresponding demodulation methods. Typical contents
include basic concepts of angle modulation, power of anglemodulated signal, frequency spectrum of angle-modulated signal,
discrimination method of demodulation, and phase-locked loop
(PLL) method of demodulation. Some time may be spent on
introducing noise effects on angle-modulated signals.
Review of Probability
Reviews some concepts in Probability, in preparation for discussion
of Random Processes (the next subject unit).
Random Processes
Also known as stochastic processes. In communication system
design and analysis, it is often convenient or even necessary to
represent the transmitted signal or the encountered noise as a
random process, that is, random waveforms that appear according to
some probability distribution. This unit introduces some basic
concepts of random processes, their statistical characterization (such
as stationarity), and how a linear system affects the property of a
random process (such as the input-output relationship of a linear
system and lowpass representation of a bandpass process). Some
time may also be spent on introducing some commonly encountered
noise sources in communication circuits and commonly used ways
of characterizing noise effects in communication systems.
Performance of Analog Modulation
Methods in Noise
Uses the concepts taught in Random Processes (last subject unit) to
analyze the transmission performance of various linear and angle
modulation methods.
Introduction to Digital Communication
An introduction to digital communication. Contents may include
signal-space analysis, baseband digital signal transmission
techniques, and passband digital signal transmission techniques.
