Chapter 3 part 1

Given electronic signal has a level of voltage from 0-2V is:

• low -> bit 0

• high -> bit 1.

Given electronic signal has a level of voltage from 2-5V is:

• high -> bit 1.

• low -> bit 0

A device that performs a basic operation on electrical signals is:

Gates combined to perform more complicated tasks is:

How do we describe the behavior of gates and circuits?

• Boolean expressions

• Logic diagrams

• Truth tables

• Algorithm

How many types of gates ?

• 6

• 3

• 4

• 5

Gate accepts one input signal (0 or 1) and returns the opposite signal as output is :

• Not

• Nand

• Xor

• Or

Gate accepts two input signals If both are 1, the output is 1; otherwise, the output is 0 is:

• Nor

• And

• Xor

• Nand

Gate accepts two input signals If both are 0, the output is 0; otherwise, the output is 1

• And

• Xor

• Or

• Nor

Gate accepts two input signals If both are the same, the output is 0; otherwise, the output is 1… same as binary addition except for the carry is:

• Xor

• Nor

• And

• Not
