Question 1 of 10
Which logic gate produces a HIGH output only when all inputs are HIGH?
The AND gate requires all inputs to be HIGH (1) to produce a HIGH (1) output.
Question 2 of 10
What is the function of an encoder in digital systems?
An encoder's primary function is to transform various forms of data into a binary code for processing or transmission.
Question 3 of 10
Which gate is the inverse of an AND gate?
The NAND gate is a combination of an AND gate followed by a NOT gate, effectively inverting the AND function.
Question 4 of 10
What is the primary purpose of a multiplexer?
A multiplexer selects one of several input signals and forwards it to a single output.
Question 5 of 10
Which logic operation produces a LOW output only if all inputs are HIGH?
NAND gate is the inverse of the AND gate; it gives a low output only when all inputs are high.
Question 6 of 10
What is the result of the logical operation 1 AND 0?
In an AND operation, the output is 1 only if both inputs are 1. Here, one input is 0, so the output is 0.
Question 7 of 10
Which of the following is NOT a common digital logic operation?
Differentiation is a calculus operation, not a fundamental digital logic operation. Addition, subtraction, and multiplication are performed using digital circuits.
Question 8 of 10
What does a decoder do?
A decoder performs the inverse function of an encoder, translating a binary code back to its original representation.
Question 9 of 10
Which gate outputs HIGH if an odd number of inputs are HIGH?
The XOR (exclusive OR) gate outputs a high signal when the number of high inputs is odd.
Question 10 of 10
What type of circuit is used to perform the arithmetic operation of subtraction?
A subtractor circuit is specifically designed to perform the subtraction operation in digital systems.
