Question

What happens to the state of a variable if it goes through a two series connected NOT gate.

Answer 1

`\begin{gathered} \text{variable}=x \\ x\text{ }\rightarrow\text{ NOT}\rightarrow\text{ Not x}\rightarrow NOT\rightarrow x \\ \text{Hence the state of a variable if it goes througha two series connected} \\ \text{NOT gate doesn´t change} \end{gathered}`
