3.4 Determine a realization of the system that requires the minimum possible amount of memory (least number of delay blocks). 3.5 Determine if the system is stable. Explain your answer.

Q1: Design a control of an Oil Tank based on MCU to drive a pump. The pump will feed the tank when the level of oil becomes less than Min. and turn off when the level of oil exceeds Max, level as shown in Figure 1. There are two sensors S1, and $2 with logical output (logic [1]-5V, and logic (0)-0V). These sensors are connected to the MCU to turn on or tum off the pump depending on the above scenario. 52 Pump driver OMCU Figure 1: MCU based design.

Not familiar with registers? indirect addressing method? What is the H? Explain the concept and answer below pls!

5. Consider automatic doors that open and close at the grocery store. Sensors on the ground tell the door when to open and close. a. Describe the operation of a one-way door. Each sensor provides a binary input indicating whether or not a person is there. Specifically, identify the different states the operation might be in (e.g. both sensors off, door closed or one sensor on, door open, etc). Figure out the transitions between states and what the triggers for the transition are. b. Design a circuit to implement this state machine. These doors have sensors on both sides because (1) the door should not hit anyone standing outside, and (2) you don't want the door to close in somebody's face. To clarify, you are only designing the circuit for one door. These doors are typically installed in pairs, one for "in" and one for "out". Each door will have its own circuit
