Front

What are the UNIVERSAL GATES?

Back

NAND Gate & NOR Gate.

Front

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

Back

2.

Front

What is the symbol for a NAND gate?

Back

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

Front

What is the output state of a NAND gate when both inputs are low (logic level 0)?

Back

1.

Front

Which truth table corresponds to the XOR gate?

Back

The XOR gate outputs true only when the inputs are different.

Front

Define a logic gate.

Back

A logic gate is an electronic component that operates on one or more binary inputs to produce a single binary output.

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 output of a NOR gate when both inputs are high (logic level 1)?

Back

0.

Front

Explain the difference between NAND and NOR gates.

Back

NAND gates output false only when all inputs are true, while NOR gates output true only when all inputs are false.
