True$/$False Questions$[12]$i$)$ If the output of a gate is OFF when the inputs are the same, and ON when they are different, the gate must be an exclusive$-$OR$.$ii For two's complement numbers, the negative of a number can be found by adding oneand then inverting the bits.ii A computer will use ASCII code to store information internally. iv$)$ A disadvantage of two's complement numbers is that, unlike a sign$-$and magnitude representation, you cannot tell if a number is negative by looking at only one bit.v$)$ The number of rows of a truth table depends on the number of inputs, not the number of outputs.vi$)$ If a wire carries a logical value of $0,$ its voltage level will be $0$ Volts. vii$)$ In an S$-$R Latch, if both S and R inputs are asserted, Q and Q will both be O viii$)$ The Boolean expression for a three$-$input AND gate is Y $=$ A B $+$ C$.$ ix$)$ According to the commutative law, in ORing and ANDing of two variables, the orderin which the variables are ORed or ANDed makes no differencex$)$ An $8-$to$-1$ multiplexer requires $2$ select lines. xi$)$ A half adder has a carry input.xii$)$ If a decoder has $16$ outputs, it requires $3$ inputs to choose all possible outputs.
