Question

Q2) The following is a Boolean expression of a Combinational Logic Circuit. Construct the truth table and a Combinational Logic circuit using AND, OR and NOT logic gates for the Boolean expression. Redraw the logic circuit using only NAND gates. 19 Marks) X = A B C +ABC + ABC

Answer 1

Deuth table far given enpresa & ABC + ABC x = ABC at As we know AND and truth OR table Gate OR Gate AND Gate tooft - odol - d - do + 7o Brith - table for x= ABC + ABC + ABC

DAVE 0-0 0-0- - - X= ABC + ABC + ABC Logic circuit : using AND, OR ar NOT Gate ABC A ABC

CADENO.: DATE: 1 logic circuit eising only NAND gate La tot ce - ABC ABC HABE
