The output of an AND gate is (a) only when all inputs are 1.
A NAND gate is equivalent to an AND gate followed by a (a) gate.
The XOR gate outputs 1 only when the number of 1 inputs is (a)
The truth table for a NOR gate has all outputs as (a) when all inputs are 0
The expression A+B with a line on top represents (a) gate
When combining gates, the gate that outputs 1 only if both inputs are 1 is the (a) gate.
What does the NOT gate look like
a triangle
an arc with a circle
triangle with a circle
heart with circle
Whats the input of an AND gate if both inputs are 1
0
1
depends on the inputs

AND
OR
XOR
NAND
The output of a NAND gate is always the _____ of an AND gate output

None of the above
What does the truth table of a NOR gate look like when both inputs are 0
0
1
depends on input
cannot be determined
which gates output is true when at least one input is true
AND
OR
NOT
XOR
The output of NOR gate is 1 when:
All inputs are 1
at least 1 input is 1
all inputs are 0
none of the above
