Experiment No. 3 bsc.3nd semester
(To study and verify the truth table of x - OR , x - NOR gate . )
Object
To study and verify the truth table I XOR gate and NOR
gate .
Apparatus Required
Bread board connecting wires DC power supply
. logic gate .
Theory
Logic gate are electronic circuits which performs logic funcations or are one or more inputs to produce one output the input / output
combination I gates is called truth table .
Exclusive OR Gate
XOR gate is a logic gate the gives a truth
output . when the number I true OR from mathematical logic … that is a true
output results if one and any one I the inputs to the gate is true if both
inputs are false or both are true a false output results . An XOR gate is
obtained by using OR , AND one Output .
The Boolean expression for
the XOR gate is .
Y = A . B Bar + Ᾱ . B
Exclusive NOR Gate
X NOR is
digital logic gate that outputs true (1) , when an even number I true
inputs are present . it produces a true output if both I it inputs are the same
( either both true or both false . )
This gate also has two inputs
and one output it is a combination I XOR gate followed by an inverter Boolean
expression for X NOR gate is .
Y = A .B + Ᾱ . B Bar
