6. Write a Boolean equation and logic circuit for each situation
i. Amran will watch a HBO movie if Opah comes along and it does not rain.
LOGIC CIRCUIT:
LEGEND:
W = Watch a HBO movie
O = Opah comes along
R = Rain
W= O . R’

ii. The entrance door will be automatically unlocked if the time is within office hours (0800-
1500), on a weekday (Monday-Friday) and it is not a public holiday.
LOGIC CIRCUIT:
LEGEND:
U= unlocked
T= Time
W= Weekday
H= Public holiday
U= W.T.H’

iii. Every participant must wear a red or yellow T-shirt, and a pair of dancing shoes to be
eligible for the competition, but miniskirts are not allowed.
LOGIC CIRCUIT:
LEGEND:
E= eligible for the competition
R= Red T-shirt
Y= Yellow T-shirt
S= wear dancing shoes
M=wear miniskirts
E= (R+Y) . S . M’

7.

a. Determine a single logic gate to b. Determine a single logic gate to
replace the logic circuit below. replace the logic circuit below.

NOR NAND

***NOTE:

1. A’.B’ ≠ (AB)’

2. A’+ B’ ≠ (A + B)’
