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
