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
