Question

Write the Boolean expression (in Sum of Products form) for the logic circuit that will have a 1 output when A = 0, B = 0, C = 1 and A = 1, B= 1, C= 0, and a zero (0) output for all other input states. Draw the logic diagram for this circuit. 

Answer 1

Gives

A=1,B=1,C=0

A=1,B=0,C=1

A=0,B=0,C=0

$Y=\overline{A}.\overline{B}.C+A.B .\overline{C}$

$Y=\overline{A}.\overline{B}\bigoplus C$
