GATE | GATE-CS-2002 | Question 27
Consider the following multiplexor where 10, 11, 12, 13 are four data input lines selected by two address line combinations A1A0 = 00, 01, 10, 11 respectively and f is “the output of the multiplexor. EN is the enable input.
F = (XYZ’ +XYZ + Y’ZY + ZY’)Z’
F = (XYZ’ +XYZ + ZY'(Y + 1))Z’
F = (XYZ’ +XYZ + ZY’ * 1)Z’
F = (XY(Z’ + Z) + ZY’)Z’
F = (XY + ZY’)Z’
F = XYZ’ + 0
F = XYZ’
Thus, option (A) is correct.
