Question 9:
x.x = x
Answer: True
Question 10:
The Boolean function F(x,y,z) = (y+x)(y+x1)(y1+z) is equivalent to:
Answer: yz
Explanation:
(y+x)(y+x1)(y1+z)
= (y.y+yx1+xy+x.x1)(y1+z)
= (y+yx1+xy+0)(y1+z) [ since y.y = y and x.x1 = 0 ]
= (y+xy)(y1+z) [ since y+yx1 = y ]
= (yy1+yz+xy.y1+xyz)
= (0+yz+0+xyz) [ since y.y1 = 0 ]
= (yz(1+x)
= yz [ since 1+x = 1 ]

Question 22 4 pts Find the sum-of-prime-implicants form of the following Boolean expression: xy +2'z+yz' + xyz xy + xz+y O xy + y2 + 2 OX'z+y+z' O2 + y + 2 None of the above.
With the following Boolean function f1(x, y, z) = xy+yz+xz draw the components of a 3-LUT …..Be sure to label all of the components including least significant bit and most significant bit of the MUX select lines and number its inputs How many different functions can be generated by a 3-LUT function generator?
Use the gradient rules to find the gradient of the given function, f(x,y,z) = x+yz y+xz Choose the correct answer below. 1 O A. Vf(x,y,z) = -((1-z?)z(z2 - 1).y? - x?) (y + xz)? OB. Vf(x,y,z) = (z(1-z?)y(z? - 1),z2 + x2) (x + yz)? O c. Vf(x,y,z) = (y(1+z2),x(z? + 1).y? - z?) (x + yz)? OD. Vf(x,y,z) = -(y (1-2²), x(2² - 1), y² - x²) (y + xz)2
A truth table can be implemented with different boolean expressions and different circuits True False Question 5 (2 points) The boolean expression "not x or y" is equivalent to the boolean expression "x or not Y" True False Question 6 (2 points) The boolean expression (x or y) and x is equivalent to the boolean expression (x and y) ory True False
If z = xy + xf (?), then xgie + y + z = xy. O True O Falsem 11== f ($x + 2), then 29. – 3.3 -1. then O True False If z = , then x2 + y a = 2 True 0 False If w = f (xz, yz), then xy + y O True 0 False
Construct a truth table then simplify the following functional expressions: a) F(x,y,z) = xyz + x(yz)' + x'(y+z) + (xyz)' b) F(x,y,z) = y(x'z + xz') + x(yz + yz')
