Unformatted text preview: abd b) F = abc + acd + bcd + ac + abd The above expression is an AND OR circuit realization for F. c) F = (a + c)(b + c + d)(a + b + d)(a + c + d)(a + b + c) The above expression is an OR AND circuit realization for F. 6) A = B = C = 1, so F = (A + B + C)(A + B + C)(A+ B + C) = 1 But, in the figure, gate 4 outputs F = 0, indicating that something is wrong. For the last NOR gate, F = 1 only when all its inputs are 0. But the output of the gate is 1. Therefore, gate 4 is working properly, but gate 1 is connected incorrectly or is malfunctioning. 7) e is the output of the inverter...
