1 Write out an expression for the following circuit A B C D A B C C D 2 These problems will have you rewriting logical expressions to only use specific operations then draw the circuit diagrams a Rewrite C A M E L using only negation or gates and draw the corresponding circuit diagram C A M E L b Rewrite A B C using only nor gates and draw the corresponding circuit dia gram For simplicity in the expression NOR of something with itself is notated as NOT however the circuit diagram explicitly shows NOR with the same input twice A B C 3 These problems will have you rewriting logical expressions to only use specific operations then draw the circuit diagrams a Rewrite C A M L using only negation or gates and draw the corresponding circuit diagram C A M L C A M L C A M L So this is then equal to this circuit diagram b Rewrite A B C using only nand gates and draw the corresponding circuit diagram A B C A B C A B C So this is then equal to this circuit diagram 4 Condense the following expression to use as few gates as possible You are allowed to use and or not nand nor xor gates Draw the corresponding circuit diagram and show your simplification work Feel free to compare with others Note we ll be giving plenty of partial credit so just try your best A B C D A B The most condensed expression we found was A B C D which uses 3 gates total Here is the circuit diagram for it 1 5 Write an expression for the following circuit A B C A B B C 6 Draw a circuit for the following expression A B A B 2
