4
Q
What is a logic gate?
A
A device that receives one or more electric input signals and produces an output signal that depends on those input signals
5
Q
What is the equivalent of a NAND gate?
A
An AND gate going into a NOT gate
6
Q
What is the equivalent of a NOR gate?
A
An OR gate going into a NOT gate
7
Q
How does a NAND gate work?
A
The output is 1 so long as the first and second input are NOT both 1
