OR GATE

OR GATE

Ø OR gate is a gate of Addition.

Ø OR gate is a gate with two more input signal and to get a only one output signal.

Ø If both input signal is LOW then to get a LOW output signal otherwise to get a HIGH output signal.

Ø Now we check Condition…

(1) A=0,B=0

Y=A+B

0+0

0

(2)A=0,B=1

Y=A+B

0+1

1

(3)A=1,B=0

Y=A+B

1+0

1

(4)A=1,B=1

Y=A+B

1+1

1

Ø If we take A=0 and B=0 then to get a low output signal because of OR gate is a gate with two or more input signal and to get a only one output signal. If both input signal is LOW then to get a LOW output signal otherwise to get a HIGH output signal.

Ø If we take A=0 and B=1 then to get a HIGH output signal because of OR gate is a gate with two or more input signal and to get a only one output signal. If both input signal is LOW then to get a LOW output signal otherwise to get a HIGH output signal.

Ø If we take A=1 and B=1 then to get a HIGH output signal because of OR gate is a gate with two or more input signal and to get a only one output signal. If both input signal is LOW then to get a LOW output signal otherwise to get a HIGH output signal.

Ø If we take A=1 and B=1 then to get a HIGH output signal because of OR gate is a gate with two or more input signal and to get a only one output signal. If both input signal is LOW then to get a LOW output signal otherwise to get a HIGH output signal.
