Hello one more quesstion came up
here we go :
A candy bar manufacturing company requires a digital system that can take ingredients from 3 different containers in a proper proportion as shown in the figure below, and mix any 2 of them to make the final product. The mixing system has two outputs for indicating an invalid/ not allowable condition by a warning buzzer and normal condition by normal operation. The three ingredients are supplied by 3 different logic circuits. The circuits have following conditions:
The logic circuit Ia: should output HIGH when the ingredient A's quantity=8
The logic circuit Ib: should output HIGH when the ingredient B's quantity=4
The logic circuit Ic: should output HIGH when the ingredient C's quantity=2
The outputs of these three logic circuits are connected with mixing system (logic circuit M). The mixing system should combine any two of the ingredients. Therefore, if exactly 3 inputs of the mixing circuit are high the warning buzzer should turn on & normal operation of. otherwise normal operation indicator should remain on & warning oFf.

This is the cirucit that came with the question
Truth table that I have made:
A B C Output
0 0 0 0
0 0 1 0
0 1 0 0
0 1 1 1
1 0 0 0
1 0 1 1
1 1 0 1
1 1 1 warning buzzer
now tell me what should I do ?
