CHAPTER 1
INTRODUCTORY CONCEPTS

Section 1-1 Digital and Analog Quantities

1. 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.

2. Pressure is an analog quantity.

3. A clock, a thermometer, and a speedometer can have either an analog or a digital output.


Section 1-2 Binary Digits, Logic Levels, and Digital Waveforms
4. In positive logic, a1 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.

5. HIGH = 1; LOW = 0. See Figure 1-1.




6. 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
