LOGIC GATE

                                                             LOGIC GATES
-WHAT IS USE LOGIC GATE??
       Logic gates perform basic logical function and is the fundamental of building circuit. Most logic gates will
have 2 input and will have output as 0 (false) and 1(true). That are few types of logic gates that are commonly used .....

NAME	BOLLEAN EQUATION	TRUTH TABLE			DIAGRAM
		A       B        F
AND	Y=A∙B	0 0 1 1	0 1 0 1	0 0 0 1
OR	Y=A+B	0 0 1 1	0 1 0 1	0 1 1 1
NOT	Y=A’	0 1		1 0
NAND	Y=(A∙B)’	0 0 1 1	0 1 0 1	1 1 1 0
NOR	Y=(A+B)’	0 0 1 1	0 1 0 1	1 0 0 0
XOR	Y=A∙B’+A’∙B	0 0 1 1	0 1 0 1	0∙1+1∙0=0 0∙0+1∙1=1 1∙1+0∙0=1 1∙0+0∙1=0

Among all logic gates, XOR gate will be a bit complex... The output will only be TRUE when exactly one of
the input is TRUE..... here are table that simply the above messy truth table FOR XOR GATE...

Input A	Input B	Output
FALSE	FALSE	FALSE
FALSE	TRUE	TRUE
TRUE	FALSE	TRUE
TRUE	TRUE	FALSE

here is the link that can refer to know more about logic gates, it is simple and easy !!!http://www.wisc-online.com/Objects/ViewObject.aspx?ID=dig1302....
