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

9. F = 0.25 Khz = 250 Hz
= T 4 Ms

10. The Waveform In Figure 1-61 Is Periodic Because It Repeats At A Fixed Interval.

11. Tw = 2 Ms; T = 4 Ms
Tw 2 Ms
% Duty Cycle =  100   100 = 50%
T 4 Ms

12. See Figure 1-4.
