4. Design a digital circuit using three D flip-flops to control the shutdown sequence for an industrial dishwasher. The systems engineer has provided the following specification: The control circuit has one input: E (enable) The control circuit has three outputs: A, B, C When E= 0, the state of the circuit remains the same. When E= 1, the circuit outputs go through the transitions from 000 to 111 to 011 to 101, to 001, back to 000, and then repeats. Use the given signal names for the variables in your solution (E, A, B, C). Do not substitute different variable names. The flip-flop states should be the outputs. That is, make the flip-flop outputs the circuit outputs. Use don't cares in your solution for all unused states.

An electronic system will only operate if three switches A, B and C are correctly set. An output signal (X = 1) will occur if A and B are both in the ON position or if A is in the OFF position and B and C are both in the ON position. Design a logic circuit to represent the above situation and draw the truth table and Karnaugh diagram
. 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.
Create a decade counter using Toggle flip-flops. The sequential circuit should contain four flip-flops whose outputs form a code word interpreted as a BCD-coded decimal value (0000 for 0, …, 1001 for 9). On each clock pulse, the coded value is incremented, and when it reaches 9, it returns to 0 on the next clock pulse. On the 9-to-0 transition, the circuit activates an output line (c) to indicate the counter overflowed. (LO2, LO3) Question 1. Show the state diagram for the circuit you are going to create.

Assume that you are given the task of designing a logic circuit to help determine the best time to plan a garden. There are three possible factors: 1) Time, where 0 represents day and 1 represents evening; 2) Moon, where 0 represents 20 Celsius and below, and 1 represents over 20 Celsius. These three factors represent inputs. After significant experimentation, it was found that the best time to plan a garden is during the evening with a full moon (temperature does not appear to matter. This results in the following truth table. Time (x) Moon (y) Temperature (z) Pant? 0 0 0 0 0 0 1 0 0 1 0 0 0 1 1 0 1 0 0 0 1 0 1 0 1 1 0 1 1 1 1 1 Convert the truth table to a Boolean function F, in its simplified form, and draw a logic gate which equivalent to the function.
