Which gate is equivalent gate?

Which gate is equivalent gate?

A NAND gate is equivalent to an inverted-input OR gate. An AND gate is equivalent to an inverted-input NOR gate.

What is the input of OR gate?

The OR gate is an electronic circuit that gives a high output (1) if one or more of its inputs are high. A plus (+) is used to show the OR operation. The NOT gate is an electronic circuit that produces an inverted version of the input at its output. It is also known as an inverter.

Which is not a basic gate?

Answer: NOR gate is not the basic logic gate.

Where are logic gates used in real life?

But, in practice, the basic logic gates are built using CMOS technology, MOSFET(Metal Oxide Semiconductor FET), FETS. Logic gates are used in microcontrollers, microprocessors, electronic and electrical project circuits, and embedded system applications.

Which is the combination of and NOT gate?

This basic logic gate is the combination of AND and NOT gate. This gate is the combination of OR and NOT gate. In XOR gate the output of a two-input XOR gate attains the state 1 if one adds only input attains the state 1. A. B ˉ + A ˉ. B In XNOR gate the output is in state 1 when its both inputs are the same that is, both 0 or both 1.

What is the Boolean expression of i n or gate?

I n OR gate the output of an OR gate attains the state 1 if one or more inputs attain the state 1. The Boolean expression of OR gate is Y = A + B, read as Y equals A ‘OR’ B. The truth table of a two-input OR basic gate is given as;

When does the output of an OR gate attain the state?

I n OR gate the output of an OR gate attains the state 1 if one or more inputs attain the state 1. The Boolean expression of OR gate is Y = A + B, read as Y equals A ‘OR’ B. In AND gate the output of an AND gate attains the state 1 if and only if all the inputs are in state 1.

What is the definition of the XOR gate?

(3) The ‘XOR’ gate: From ‘NOT’, ‘AND’ and ‘OR’ gate. The logic gate which gives high output (i.e., 1) if either input A or input B but not both are high (i.e. 1) is called exclusive OR gate or the XOR gate. It may be noted that if both the inputs of the XOR gate are high, then the output is low (i.e., 0).

According to De Morgan’s theorem, a NAND gate is equivalent to an OR gate with inverted inputs. Similarly, a NOR gate is equivalent to an AND gate with inverted inputs. Figure 2.19 shows these De Morgan equivalent gates for NAND and NOR gates. The two symbols shown for each function are called duals.

What is gate truth table?

The table used to represent the boolean expression of a logic gate function is commonly called a Truth Table. A logic gate truth table shows each possible input combination to the gate or circuit with the resultant output depending upon the combination of these input(s).

What is equivalence logic gate?

) from mathematical logic, also known as the material biconditional. The two-input version implements logical equality, behaving according to the truth table to the right, and hence the gate is sometimes called an “equivalence gate”. A high output (1) results if both of the inputs to the gate are the same.

Which is the equivalent of a bubbled gate?

First theorem – It states that the NAND gate is equivalent to a bubbled OR gate. Second theorem – It states that the NOR gate is equivalent to a bubbled AND gate. A + B ‾ = A ˉ. B ˉ 1) The ‘NAND’ gate: From ‘AND’ and ‘NOT’ gate.

What are the different types of logic gates?

In simple terms, logic gates are the electronic circuits in a digital system. In this lesson, we will further look at the different types of basic logic gates with their truth table and understand what each one is designed for.

How are truth tables used in logic gates?

Logic gates may be combined to form logic gate diagrams that perform more complicated logical operations. Truth tables are used to show the states of each terminal and hence the logical operations. e.g. e.g. 2) What is the algebraic expression, where variables are denoted with Boolean logic for the following logic gate diagram?

How many rows are needed for a 3 input logic gate?

For a 3-input logic gate, there are 8 possible inputs like 000, 001, 010, 011, 100, 101, 110 & 111. Therefore, a truth table including 8 rows is required. Mathematically, the required number of rows in the truth table is equivalent to 2 increased to the power of the no. of i/p terminals.
