LOGIC GATES Flashcards
To learn the different types of logic gates and to learn what truth tables give as an output
1
Q
OR
A
high output if any of the inputs are high
2
Q
AND
A
high output only if all the inputs are high
3
Q
XOR
A
similar to OR gates but output is high when ONLY ONE input is high
4
Q
NAND
A
high output unless both inputs are high
5
Q
NOT
A
high output if input is low (only one input)
6
Q
NOR
A
inverse of an OR gate - output is low when any output is high
7
Q
How does an or truth table look like for a or gate
A
A | B | C 0 | 0 |0 1 | 0 | 1 0 | 1 | 1 1 | 1 | 1
8
Q
how does an and gate look in a truth table
A
A | B | C 0 | 0 | 0 1 | 0 | 0 0 | 1 | 0 1 | 1 | 1
9
Q
how does the nor gate look in a truth table
A
A | B | C 0 | 0 | 1 1 | 0 | 0 0 | 1 | 0 1 | 1 | 0
10
Q
how does the xor gate look in a truth table
A
A | B | C 0 | 0 | 0 1 | 0 | 1 0 | 1 | 1 1 | 1 | 0
11
Q
how does the nand gate look in a truth table
A
A | B | C 0 | 0 | 1 1 | 0 | 1 0 | 1 | 1 1 | 1 | 0
12
Q
how does the not gate look in a truth table
A
A | B | C 0 | 0 | 1 1 | 0 | 0 0 | 1 | 0 1 | 1 | 0
