CHAPTER 1 
INTRODUCTORY CONCEPTS 
 
Section 1-1  Digital and Analog Quantities 
 
1. 
xuebazhushou.com
学
Digital data can be transmitted and stored more efficiently and reliably than analog data.  Also, 
digital circuits are simpler to implement and there is a greater immunity to noisy environments. 
A clock, a thermometer, and a speedometer can have either an analog or a digital output. 
Pressure is an analog quantity. 
 
2. 
 
3. 
 
 
Section 1-2  Binary Digits, Logic Levels, and Digital Waveforms 
 
4. 
In positive logic, a 1 is represented by a HIGH level and a 0 by a LOW level. In negative logic, 
a 1 is represented by a LOW level, and a 0 by a HIGH level. 
A 1 is a HIGH and a 0 is a LOW: 
(a)  HIGH, LOW, HIGH, HIGH, HIGH, LOW, HIGH 
(b)  HIGH, HIGH, HIGH, LOW, HIGH, LOW, LOW, HIGH
