Consider the following statements. P. The output of the four inputs AND gate is 1 when all the four inputs values are 1’s.
Consider the following statements.
P. The output of the four inputs AND gate is 1 when all the four inputs values are 1’s.
Q. The output of the four inputs AND gate is 0 when at least one input value is 0.
R. Three AND gates are used in the implement given three variable Boolean function F (A, B,
C) = AB +BC +AC using basic logic gates.
Which of the given statements are correct in a digital logic system?
Show answerHide answer
Correct answer: (B) P, Q, and R
Explanation
P and Q describe the AND gate correctly. For AB + BC + AC you need three AND gates (AB, BC, AC) plus OR gates, so R is also true.
