Question

state the principal of duality write the dual of ......(P+Q').R.1=P.R+Q.R
​

Answer 1

Answer:

To every Boolean equation there exists another equation which is dual to the previous equation. This is done by changing AND’s to OR’s and vice-versa, 0’s to Fs and vice-versa, complements remain unchanged. Dual: (P.Q’) + R + 0 = (P + R). (Q’+ R)
