What is a XOR gate equivalent to?
XOR gate (sometimes EOR, or EXOR and pronounced as Exclusive OR) is a digital logic gate that gives a true (1 or HIGH) output when the number of true inputs is odd. An XOR gate implements an exclusive or ( ) from mathematical logic; that is, a true output results if one, and only one, of the inputs to the gate is true.
Can we use XOR gate to check equivalency?
XOR Gate Equivalent Circuit So, the XOR circuit with 2 inputs is designed using AND, OR and NOT gates as shown below. The output of 2 input XOR gate is HIGH only when one of its inputs are HIGH. If both the inputs are same, then the output is LOW.
Which gate is equivalent to NOR OR XOR?
The XNOR gate (also known as a XORN’T, ENOR, EXNOR or NXOR) – and pronounced as Exclusive NOR – is a digital logic gate whose function is the logical complement of the exclusive OR gate (XOR gate). Logically, an XNOR gate is a NOT gate followed by an XOR gate.
What is the circuit diagram of XOR gate?
Truth Table of XOR gate
| Input (A) | Input (B) | Output, Y = A ⊕ B ⊕ C \small Y=A\oplus B\oplus C Y=A⊕B⊕C |
|---|---|---|
| 0 | 1 | 0 |
| 1 | 0 | 1 |
| 1 | 0 | 0 |
| 1 | 1 | 0 |
How do you construct an XOR gate circuit?
A circuit implementing an XOR function can be trivially constructed from an XNOR gate followed by a NOT gate. If we consider the expression, we can construct an XOR gate circuit directly using AND, OR and NOT gates. However, this approach requires five gates of three different kinds.
Is the XOR gate a complete logic gate?
These gates are not basic gates in their own and are constructed by combining with other logic gates. Their Boolean output function is significant enough to be considered as a complete logic gate. The XOR and XNOR gates are the hybrids gates.
How many inputs does a 3-input XOR gate have?
Unlike the 2-input XOR gate, the 3-input XOR gate has three inputs. There are 2 3 =8 possible combinations of inputs. The Boolean expression of the logical Ex-OR gate is as follows: The truth table and logic design are given below: We can form the XOR or Ex-OR gate using gates such as AND, OR, and a universal gate NAND.
What is the schematic of XOR gate using diodes and BJT?
Schematic of XOR gate using Diodes and BJT (NPN transistor) is given below. In which we have used two NPN transistors, 4 diodes and the resistor between Diode Bridge and NPN is used in series configuration because BJTs operates on input current, not input voltages.
