What is the purpose of the circuit below?
To perform the basic addition of two or more binary numbers.
To perform the basic addition of two binary numbers and always create the carry signal.
To perform the basic addition of two binary numbers but cannot handle a 'carry in' from previous addition.
What does a parallel adder require?
Adder logic for the number to be added.
Only one adder for the number to be added.
Adder logic for each bit of the number to be added.

Which are the three basic logic functions from which all others were created?
AND, OR, NOR
AND, OR, NOT
AND, NOR, Inverter
AND, OR, XOR
An AND gate is connected to an inductor that when energised keeps a power off flag hidden, what would the input/output logic of the AND gate be to keep the coil energised?
Inputs all at 1 to get 1 output.
Any of the inputs at 1 to get and output at 1.
An output of one is only achieved with mismatched input values.
What is the purpose of logic circuits and flow diagrams?
The represent function and the power supplies of the logic circuits.
They represent function and aid fault finding.
The diagrams are low level circuit schematics that serve only training purposes.
What would be the function of the combination of a two input AND Gate with both inputs inverted?
NOR
OR
NAND
XNOR
XOR
