Exercie 7: Find the expression of the following logic circuit A- B-

Question : see the attached picture Please write a logical function for the following circuit and then construct a truth table. Implement the circuit using only the minimum possible IC SN74LS00. Check that your table matches the output of the circuit you created.

. Design a logic circuit that controls an elevator door in a three-story building. The circuithas four inputs. M is a logic signal that indicates when an elevator is moving (M=1) or stopped (M=0).F1, F2 and F3 are floor indicator signals that are normally LOW, and they go HIGH only when theelevator is positioned at the level of that particular floor. For example, when the elevator is lined uplevel with the second floor, F2=1 and F1=F3=0. The circuit output is the OPEN signal which isnormally LOW and is to go HIGH when the elevator door is to be opened.

For the logic circuit shown below you are given the values for A, B, C, and D.  Fill in the correct values for Q, R, S and X.  You should fill in your answer either with 1 or 0. A = 1 B = 0 C = 1 D = 1 Q =  R =  S =  X =
