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 four-input AND gate?
16.
-
Write the Boolean expression for an OR gate having G, K, and L as inputs.

-
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?

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?
