Answer 1

XOR GATE

Symbol:

F1 U.B Madhu 15.11.19 D 18

Truth Table:

Output Equation: $Y = A \oplus B = \bar{A} B + A \bar{B}$

Key Points:

1) If B is always High, the output is the inverted value of the other input A, i.e. A̅.

1) The output is low when both the inputs are the same.

2) The output is high when both the inputs are different.

Explanation:

$Y = \bar{X} \oplus X = \bar{\bar{X}} X + \bar{X} \bar{X}$

$Y = X X + \bar{X} \bar{X}$

$Y = X + \bar{X}$

Y = 1
