The circuit shown in the figure has 4 boxes each described by inputs P, Q, R and outputs Y, Z withY = P ⊕ Q ⊕ R, Z = RQ + R + Q The circuit is a

Answer» Let P = 1101 Q = 1101 Yn = Pn ⊕ Qn ⊕ Rn Z = Rn Qn + Pn Rn + Qn Pn Constructing truth table So that, Rn + 1 = Zn 1 ≥ n ≥ 3 Z4 = R5(MSB) Hence, output is 00010 which show that it is a 4 bit subtractor giving P - Q.
