1000+ Working Principle of Digital Logic Questions and Answers Pdf - 2

Question: 6

What is a logic gate?

A logic gate is an elementary building block of a digital circuit. It is a circuit with one output and one or more inputs. At any given moment logic gate takes one of the two binary conditions low (0) or high (1), represented by different voltage levels.

Question: 7

What is a sequential circuit?

If the logic circuit outputs are based on, not only the inputs presented at that time, but also the previous state output, then they are called sequential circuits. The flip-flop circuit is an example of sequential circuit.

Question: 8

What is a full adder?

A full adder sums three input bits. It consists of three inputs and two outputs. Two of the inputs represent the two significant bits to be added and the third one represents the carry from the previous significant position.

Question: 9

What is flip flop?

A flip flop is a circuit which is capable of remembering the value which is given as input. It can be used as a basic memory element in a memory device. These circuits are capable of storing one bit of information.

Question: 10

What are the different types of logic gates?

There are three fundamental logic gates namely, AND, OR and not.

Also we have other logic gates like NAND, nor, XOR and XNOR. Out of these NAND and NOR gates are called the universal gates.
