C1. Consider the designing of a synchronous circuit to detect the sequence 0110. The circuit has a single input x, and a single output z. The output is logic-l whenever the input sequence 0110 is detected, logic-0 otherwise. Note that overlapping sequences are allowed. Answer the following questions: a. Complete the following state diagram of the circuit: 1 so s1 S2 S3 S4 b. Draw and fill the state table of the circuit. c. Write the equations of the state variables and the output Z.
2. Design a logic circuit that controls an elevator door in a three-story building. The circuit has 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 the elevator is positioned at the level of that particular floor. For example, when the elevator is lined up level with the second floor, F2=1 and F1=F3=0. The circuit output is the OPEN signal which is normally LOW and is to go HIGH when the elevator door is to be opened.
