MCQ (Single Correct Answer)

-0.6

The Boolean expression Y= $$\overline A \,\overline B \,\overline C \,D + \overline A BC\overline D + A\overline {B\,} \overline C \,D + AB\overline C \,\overline D $$

Y = $$\overline A \,\overline B \,\overline C \,D + \overline A B\overline C + A\overline C D$$

Y = $$\overline A \,\overline B \,\overline C \,D + BC\overline D + A\overline B \overline C \,D$$

Y=$$ \overline A \,BC\,\overline D + \overline B \,\overline C D + A\overline B \overline C \,D$$

Y= $$\overline A \,BC\,\overline D + \overline B \,\overline C D + AB\overline C \,\overline D $$

In the following circuit, X is given by GATE ECE 2007 Digital Circuits - Combinational Circuits Question 28 English

$$X = \,A\overline B \,\overline C + \overline A \,B\,\overline C + \overline A \,\overline B C + ABC$$

$$X = \,\overline A \,BC + A\overline B C + AB\overline C + \overline A \,\overline B \,\overline C $$

$$X = AB + BC + AC$$

$$X = \,\overline A \,\overline B \, + \overline B \,\overline C \, + \overline A \,\overline C $$
