    The full form of XNOR gate is 

    • Extreme NOR

    • Exclusive OR

    • Exclusive NOR

    • Extreme NOR

    Correct Answer
    A. Exclusive NOR
    Explanation
    The correct answer is "Exclusive NOR." The XNOR gate is a logic gate that produces a high output only when the number of high inputs is even. It is the complement of the XOR gate, which produces a high output when the number of high inputs is odd. Therefore, the term "Exclusive NOR" accurately describes the function of this gate.

    Truth table is logic gates diagram in table form

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The given answer is true because a truth table is indeed a logic gates diagram presented in a table format. It is used to represent the outputs of a logical expression for all possible combinations of inputs. Each row in the truth table corresponds to a specific combination of input values, and the columns represent the inputs and outputs of the logical expression. By analyzing the truth table, one can determine the behavior and logic of a given circuit or expression.

    Which truth table is displayed? - ProProfs

    Which truth table is displayed?

    • AND

    • OR

    • NOR

    • NAND

    Correct Answer
    A. OR
    Explanation
    The correct answer is "OR" because the truth table displayed represents the logical operation of the OR gate. In an OR gate, the output is true if at least one of the inputs is true. The truth table shows that when either or both of the inputs are true, the output is also true.

    Which of these is NOT a logic gate?

    • NAN

    • NAND

    • AND

    • NOR

    Correct Answer
    A. NAN
    Explanation
    NAN is not a logic gate. This is because in digital electronics, logic gates are electronic devices that perform logical operations on one or more binary inputs and produce a single binary output. The options NAND, AND, and NOR are all examples of logic gates commonly used in digital circuits. However, NAN is not a recognized logic gate in this context.

    Why is NOT gate referred to as an inverter?

    • It turns signals upside down

    • It does not allow signals in easily

    • It accepts signals and changes them to their opposite

    • It only changes zero to one

    Correct Answer
    A. It accepts signals and changes them to their opposite
    Explanation
    The NOT gate is referred to as an inverter because it accepts signals as input and changes them to their opposite. This means that if the input signal is a logic high (1), the output will be a logic low (0), and vice versa. Therefore, the NOT gate inverts or reverses the input signal, hence the term "inverter".

    Which of these is NOT an application of logic gates?

    • Door bell

    • Light switches

    • Microprocessors

    • Computer buttons

    Correct Answer
    A. Computer buttons
    Explanation
    Logic gates are electronic devices that perform logical operations on one or more input signals to produce an output signal. They are commonly used in digital circuits to perform tasks such as data processing, signal amplification, and decision making. While door bells, light switches, and microprocessors all involve the use of logic gates in their operation, computer buttons do not directly rely on logic gates for their functionality. Computer buttons are typically used for inputting commands or selecting options in a computer system, and their operation is usually based on mechanical or touch-based mechanisms rather than logical operations performed by logic gates.

    Which gate has all outputs as zero except when the 2 inputs are 1?

    Correct Answer
    AND, And, and
    Explanation
    The AND gate is the correct answer because it only produces an output of 1 when both of its inputs are 1. In all other cases, the output of the AND gate is 0. The terms "And" and "and" are variations of the same gate and also meet the criteria of having all outputs as zero except when both inputs are 1.

    Rate this question:

  • 9. 

    Which of these are TRUE about NAND gate?

    • Output is 1 when both inputs are the same

    • The output is zero when both inputs are 1

    • It is also known as NOT AND gate

    • Output is 1 when the 2 inputs are not the same

    Correct Answer(s)
    A. The output is zero when both inputs are 1
    A. It is also known as NOT AND gate
    Explanation
    A NAND gate is a digital logic gate with two or more inputs and one output. The output of a NAND gate is true (1) only when both of its inputs are false (0). Therefore, the statement "The output is zero when both inputs are 1" is true. Additionally, a NAND gate is also known as a NOT AND gate because it performs the opposite operation of an AND gate. It produces an output that is the negation of the AND gate's output. Hence, the statement "It is also known as NOT AND gate" is also true.

    Identify the logic gate - ProProfs

    Identify the logic gate

    • AND

    • NOR

    • NAND

    • OR

    Correct Answer
    A. NAND
    Explanation
    The correct answer is NAND. A NAND gate is a logic gate that produces an output of false (0) only when all of its inputs are true (1). It is the negation of the AND gate, as it performs the AND operation and then negates the output. In other words, if any of the inputs are false, the output will be true. Therefore, NAND gates are commonly used in digital circuits for their versatility and ability to implement any Boolean function.
