Chapter 4, Problem 3P

Program Plan Intro

Logic gate:

• Logic gate is an electronic circuit that is used to perform logic decisions based on the input.
• It contains one or more number of inputs and one output.
• The working of logic gate is based on the binary principle that has two states either logic 0 or logic 1.
• The output of logic gate is produced when it satisfies any of its logic conditions.
• The logic condition depends upon the type of the gates and the number of inputs.
• The primary logic gates include AND, OR, and NOT. The combinations of these gates are used to implement any of the other logic gates.

AND gate:

• The AND gate refers to a logic gate whose output will be HIGH only when all the inputs are HIGH.
• The output of AND gate will be LOW when any one of its input will be LOW.
• The symbol to represent AND gate is given below:

• The truth table for AND gate is as follows:

INPUT A	INPUT B	OUTPUT Y
0	0	0
0	1	0
1	0	0
1	1	1

NOR gate:

• NOR gate performs the inverse operation of OR gate.
• The NOR gate refers to a logic gate whose output will be HIGH only when all the inputs are LOW.
• The output of NOR gate will be LOW when any one of its input will be HIGH.
• The symbol to represent NOR gate is given below:

• The truth table for NOR gate is as follows:

INPUT A	INPUT B	OUTPUT Y
0	0	1
0	1	0
1	0	0
1	1	0
