Question

Write the SOP form of a Boolean function G, which is represented in a truth table as follows:

P	Q	R	G
0	0	0	0
0	0	1	0
0	1	0	1
0	1	1	1
1	0	0	1
1	0	1	0
1	1	0	1
1	1	1	1

Answer 1

The desired Canonical Sum-of-Product form is as following;

G = ∑(2, 3, 4, 6, 7) = P’QR’ + P’QR + PQ’R’ + PQR’ + PQR
