NOT GATE

Ø A logical inverter , sometimes called a NOT gate to differentiate it from other types of electronic inverter devices, has only one input. It reverses the logic state.

Ø NOT GATE is a gate with only single input as well as only one output signal.

Ø Output Signal is always reverse of input signal

Now we Check Condition…

(1) A=0

(2) A=1

Ø When we take A=0 then to get a HIGH output signal because of NOT gate is a gate with one input signal and one output signal. Output Signal always reverse of Input signal.

Ø When we take A=1 then to get a low output signal because of NOT gate is a gate with one input signal and one output signal. Output Signal always reverse of Input signal.
