Logic gates and type's

LOGIC GATES AND TYPES 

                                          Gates are made by semiconductor`Gates are have three more types.They are AND,OR,NOT,NOR,NAND EXT,Then AND,OR & NOT gates are univercell gates because of we made any of outputs of these three gates .

 

GATES 

                   What's a inside of gates and how its made by gate let we see.GATES are consist of diodes.Diodes are have two terminals anode and cathode,mostly its working in forward direction and lets see diagram.

 This one is OR gate inside diagram its consist of two diodes if you give any of terminal positive supply you got output other wise not yet then one more information if you give any one terminals positive supply  got output otherwise if you give two terminal positive got much outputs.

A          B          Y           '+V '        

0           0          0              0 volts

1           0           1             5 volts

0           1           1              5 volts

1            1           1            10 volts

  

A&B-INPUTS

Y     - OUTPUT

V     - VOLTAGE FROM OUTPUT

1- +5 Volts 

0- 0 Volts

AND  GATE

In above diagram is AND gates inside consist diagram its have two diodes in their two terminals but have reverse direction so you give negative supply then only its works.

DIODES

                       Diodes is semiconductor devices its have two terminals anode(A) and cathode(k) its working in only for forward direction and working in negative direction also but after breakdown voltage.

APPLICATIONS OF GATES 

                                                                          Program logic control(PLC) is consist of logic gate then using programs to control the real time machines,like a motor,big machines and welding machines ext.
