3. WHAT IS LOGIC GATE ?
A LOGIC GATE IS AN ELEMENTARY BUILDING BLOCK OF A DIGITAL
CIRCUIT.
1= HIGH
0= LOW

4. TYPES
BASIC GATES
• AND GATE
• OR GATE
• NOT GATE
• NAND GATE
• NOR GATE

5. AND GATE
Inputs Output
A B Y
0 0 0
0 1 0
1 0 0
1 1 1
Y=A.B

6. OR GATE
Input Output
A B F
0 0 0
0 1 1
1 0 1
1 1 1
F=A+B

7. NOT GATE
F = A’
Input Output
A F
0 1
1 0

8. NAND GATE
F= (A.B)’
Input Output
A B F
0 0 1
0 1 1
1 0 1
1 1 0

9. NOR GATE
F= (A+B)’
Input Output
A B F
0 0 1
0 1 0
1 0 0
1 1 0

10. LOGIC GATE VSBOOLEAN ALGEBRA
THE TABLE USED TO REPRESENT THE BOOLEAN EXPRESSION OF A LOGIC GATE
FUNCTION IS COMMONLY CALLED A TRUTH TABLE.
INPUT COMBINATION 1. – “OFF” – “OFF” OR ( 0, 0 )
INPUT COMBINATION 2. – “OFF” – “ON” OR ( 0, 1 )
INPUT COMBINATION 3. – “ON” – “OFF” OR ( 1, 0 )
INPUT COMBINATION 4. – “ON” – “ON” OR ( 1, 1 )
