 (a.) Q (not _ placed above)
 (b.) R (not _ placed above)
 (c.) V (not _ placed above)
 (d.) Z (not _ place above)

If logic 1 = 5 vdc and logic 0 = 10 vdc, what logic polarity is being used?
Positive.

If logic 1 = +2 vdc and logic 0 = 2 vdc, what logic polarity is being used?
Positive.

If logic 1 = 5 vdc and logic 0 = 0 vdc, what logic polarity is being used?
Negative.

What is the Boolean expression for the output of an AND gate that has R and S as inputs?
f = R x S.

What must be the logic state of R and S to produce the TRUE output on an AND gate?
Both must be 1s (HIGH) at the same time.

How many input combinations exist for a fourinput AND gate?
16.

Write the Boolean expression for an OR gate having G, K, and L as inputs.
f = G+K+L.

How many input combinations are possible using G, K, and L to an OR gate?
Eight.

Using inputs G, K, and L to an OR gate. How many of those combinations will produce a HIGH output?
Seven.

What is the complement of XYZ?
XYZ (not _ placed above)

In a properly functioning circuit, can both the input and output of an inverter be HIGH at the same time?
No.

A NAND gate has Z and X as inputs. What will be the output logic level if Z is HIGH and X is LOW?
HIGH.

What must be the state of the inputs to a NAND gate in order to produce a LOW output?
All inputs must be HIGH.

A NAND gate has inputs labeled as A, B(not), and C. If A and B(not) are HIGH, C must be at what logic level to produce a HIGH output?
Low.

How does a NOR gate differ from an OR gate?
It has an inverter on the output.

What will be the output of a NOR gate when both inputs are HIGH?
Low.

In what state must the inputs to a NOR gate be in order to produce a logic 1 output?
All inputs must be low.

What is the output Boolean expression for an AND gate with A and B as inputs when the B input is inverted?
A B(not)

What is the equivalent logic gate of a twoinput NAND gate with both inputs inverted?
OR gate.
