Logic gates and truth tables
(a) Complete the following truth table for the XOR logic gate.\begin{tabular}{|c|c|c|}\hline Input A & Input B & Output Q \\\hline 0 & 0 & \\\hline 0 & 1 & \\\hline 1 & 0 & \\\hline 1 & 1 & \\\hline\end{tabular}(b) Draw logic circuits for the following Boolean expressions:(i) $Q=A \underline{\vee} \vee \neg B$(ii) $Q=\neg A \wedge B \vee C$(iii) $Q=\neg(A \vee B) \vee(A \wedge C)$
The figure below shows a logic circuit.(a) Write the equivalent Boolean expression.(b) What are the values of $F, G, H, K$ and $Q$ if $A, B, C$ and $D$ and $E$ are all equal 1 ?
Three sensors $A, B$ and $C$ are used to monitor a process. A signal $X$ is output from the circuit.$X$ has the value 1 if either of the following conditions are met:Sensor A outputs 1 AND sensor B outputs 0Sensor B outputs 1 OR sensor $C$ outputs 0Draw a logic circuit to represent these conditions.
