QUESTION 2

Suppose you are creating a truth table with 3 inputs (a, b, andc) and 1 output (F). If an 'x' symbol indicates \"don't care\" (thevalue of the input does not effect the output), how many inputcombinations are covered by the single row of a truth table shownbelow?

a	b	c	F
x	1	x	1

	-	1
	-	2
	-	3
	-	4
	-	None of the above

QUESTION 3

Suppose you have a 4x1 multiplexer (MUX) whose inputs are shownbelow in a single row of a truth table. The inputs i0 -i3 are data inputs and s0 and s1 areselector bits. What Boolean value will the data output, d,be for this row?

i3	i2	i1	i0	s1	s0	d
1	1	0	1	0	1	?

	-	0
	-	1
	-	2
	-	3

QUESTION 4

Suppose you have a 4x1 multiplexer (MUX) whose inputs are shownbelow in a single row of a truth table. The inputs i0 -i3 are data inputs and s0 and s1 areselector bits. What Boolean value will the data output, d,be for this row?

i3	i2	i1	i0	s1	s0	d
1	1	0	1	0	0	?

0	1	1	1	1	1	?

-		0
-		1
-		2
-		3

QUESTION 7

What value will the data outputs, e1 ande0, be for this row (assume d3 is the highestpriority input and results in the largest encoded value)?

d3	d2	d1	d0
0	1	1	1

-		e1 e0 0 0
-		e1 e0 0 1
-		e1 e0 1 0
-		e1 e0 1 1

What value will the data outputs, e1 ande0, be for this row (assume d3 is the highestpriority input and results in the largest encoded value)?

d3	d2	d1	d0
0	0	0	1

-		e1 e0 0 0
-		e1 e0 0 1
-		e1 e0 1 0
-		e1 e0 1 1
