Consider the circuit shown below. The output of a 2:1 Mux is given by the function (ac’ + bc).
Which of the following is true?
Correct Answer: C
Question 47 Explanation:
g = (a and x1′) or (b and x1)
g = (1 and x1’) or (0 and x1)
g = x1’
g = (1 and x1’) or (0 and x1)
g = x1’
f = ac’ + bc
f = (a and x2′) or (b and x2)
f = (g and x2′) or (x1 and x2)
f = x1’x2’ + x1x2
f = x1′ + x2
f = x1’x2 + x1x2′
f = x1x2 + x1’x2′
f = x1 + x2′
