Know Everything About Logic Gate! Electronic Quiz - Quiz

In the practice of electronics, a logic gate is a device which carries out a logical operation on a certain number of binary inputs and produces just one binary output. In the following quiz, we aim to put your knowledge on these logic gates to the test, offering up tables, diagrams and more to gauge the level of understanding you have on the topic. Think you can get them all right? Let’s find out!

Questions and Answers

1.

State the name of the logic gate shown.
- A.
  
  NAND Gate
- B.
  
  NOR Gate
- C.
  
  NOT Gate
- D.
  
  OR Gate
- E.
  
  AND Gate
Correct Answer
D. OR Gate

Explanation
The given logic gate is an OR gate. An OR gate is a digital logic gate that outputs true (1) if at least one of its inputs is true. In this case, the gate is represented by a symbol that resembles the letter "O", which is commonly used to represent an OR gate.

2.

Which logic gate does this truth table belong to?
- A.
  
  AND Gate
- B.
  
  NAND Gate
- C.
  
  OR Gate
- D.
  
  NOR Gate
- E.
  
  NOT Gate
- F.
  
  None of the above
Correct Answer
B. NAND Gate

Explanation
The given truth table represents a NAND gate. A NAND gate produces a low output only when both of its inputs are high. In all other cases, it produces a high output. By looking at the truth table, we can see that the output is low (0) only when both inputs are high (1,1). In all other cases, the output is high (1). Therefore, the given truth table matches the behavior of a NAND gate.

3.

Identify the truth table for a NOR gate.
- A.
- B.
- C.
- D.
- E.
  
  None of the above
Correct Answer
A.
4.

Identify the symbol used to represent the NOT gate.
- A.
- B.
- C.
- D.
- E.
  
  None of the above
Correct Answer
E. None of the above

Explanation
The question asks for the symbol used to represent the NOT gate. However, the answer states "None of the above," indicating that none of the options provided in the question are correct. Since the question does not provide any options, it is not possible to determine the correct symbol for the NOT gate.
