TRUTH TABLE IN ENGINEERING?

Using Truth Table, prove that


C = (A鈥?+ B)鈥?= A . B鈥?


where A, B and C are binary logical variables. Show a diagram showing the output C from inputs A and B using 鈥?-input NOR鈥?gates only.





please help! thank you in advance(:|||Use one Nor gate with its inputs tied together to make a Not gate (inverter) and connect B to the input and the output to the second Nor gate which has A as its other input.
