Lamp Test-

This is used to check the segment of LED. For normal operation it is connected to logic 1. If it is connected to logic 0 then all LED’s segments of the display will be on.

Half Adder-

Half adder is a logic circuit which is used to perform addition of two single bits. If consists of Ex-OR gate to give some result. Half adder has two inputs and two outputs.

Demorgans theorem-

First theorem-
Compliment of sum of variable is nothing but product of compliment of variables.

Second theorem-
Compliment of product of variable us nothing but compliment of sum of variable.

EX-NOR gate-

EX-NOR gate is an electronic circuit having more than two inputs and only one output. This gate is called by giving output of EX-OR gate to the NOT gate so that output of EX-NOR gate is nothing but compliment of EX-OR gate. The output of these gate is 1 when both the inputs are same. Otherwise output is 0. so these gate is also called as equality detector.

Applications of EX-OR gate-

1) Control inverter
2) Parity generator
3) Parity checker
4) Binary to gray
5) Gray to binary converter

EX-OR gate-

EX-OR gate is an electronic circuit having two or more input but only one output. When input are different then output of EX-OR gate is high and when inputs are same then output is low or logic 0. So this gate is also called as inequality detector.
