1. Indicate whether the following statements are true or false (5 pts each) An analog system contains devices that manipulate physical quantities that are represented in digital form; the quantity varies over a continuous range of values. a. If false, make the corrections: A digital system is most often electronic; however, it can also be mechanical, magnetic, or pneumatic. b. If false, make the corrections Boolean Algebra has four constants: 0, 1. True and False. If false, make the corections: c. d. TTL and CMOS are two technologies used in implementing logic gates. Standard 5V CMOS technology requires inputs for logic 0 to be in the range 0 e. 1.5V, while logic 1 inputs to be in the range 3.5-> 5V. While, standard TTL technology requires inputs for logic 0 to be in the range 0 0.8V and logic 1 to be in the range 2 -> 5V. If false, make the corrections:

Answer 1

a)false

Analog systems are the systems where proportional values are used.the analog system won't have discrete steps of change neither increasing nor decreasing.Analog systems have continuous change with finite or infinite variability

b)true

c)false

True and false in boolean algebra is represesnted with 1 and 0 respectively.only 2 values 1 and 0 are used in boolean algebra

d)true

e)false

For cmos technology logic 0 or "low" is in range 0->1.5 v logic 1 in range 3.5->5 v

For ttl technology logic 0 or "high" is in range 0->0.8 logic 1 range 2 ->5 v
