Front

What is the function of an AND gate?

Back

An AND gate outputs true (1) only if all its inputs are true (1).

Front

What is the function of an OR gate?

Back

An OR gate outputs true (1) if at least one of its inputs is true (1).

Front

What is the function of a NOT gate?

Back

A NOT gate outputs the opposite value of its input; if the input is true (1), the output is false (0), and vice versa.

Front

What are universal gates?

Back

Universal gates are gates that can be used to create any other type of logic gate. The NAND and NOR gates are considered universal gates.

Front

How many inputs can an AND gate have?

Back

An AND gate can have two or more inputs.

Front

What is the symbol for a NAND gate?

Back

The symbol for a NAND gate is similar to an AND gate but with a small circle (representing NOT) at the output.

Front

What is the symbol for a NOR gate?

Back

The symbol for a NOR gate is similar to an OR gate but with a small circle (representing NOT) at the output.

Front

What is a truth table?

Back

A truth table is a mathematical table used to determine the output of a logic gate for all possible input combinations.

Front

How many AND gates are required to realize Y = CD + EF + G?

Back

2 AND gates are required.

Front

What is the output of an OR gate with inputs 0 and 1?

Back

The output is 1.
