<img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/p-d5sytmdx6ldesmci.jpg" /> The boolean expression of this arrangement is , For NOT gate Y1= barA , Y2= barB For OR gate Y=Y1+Y2 Y= barA+ barB Y= barA ⋅ B Truth Table 1 Hence, it is clear that option 3 are correct.

Q. Input waveforms A and B as shown in figure-I are applied· to the combination of gates shown in figure-II. Which of the following waveforms shown in figures (i) to (iv) correctly represents the output waveform?

Figure (i)

Figure (ii)

Figure (iii)

Figure (iv)

The boolean expression of this arrangement is ,
For $NOT$ gate
$Y_{1} = \overset{ˉ}{A}$ , $Y_{2} = \overset{ˉ}{B}$
For $OR$ gate
$Y = Y_{1} + Y_{2}$
$Y = \overset{ˉ}{A} + \overset{ˉ}{B}$
$Y = \overset{ˉ}{A \cdot B}$
Truth Table

1

Hence, it is clear that option $3$ are correct.
