Problem Statement: Suppose you are a senior Design Engineer of Walton group. The company wants to launch a new Smart Air conditioner (S-AC). A temperature sensor will be attached to the system to measure the Room temperature (X). If X is greater than 24 degrees, the power switch will turn on automatically. The motor and compressor will start cooling operation. The system response will be saturated as soon as the room temperature reaches 20 degrees to reduce the power consumption. The transfer function of the system is - G(s) = 0-39 s+1.5 Now, 1. Considering the effects of nonlinearities, design a suitable system that can fulfill the above requirement. 2. Generate step response of the designed system for both open loop and closed loop configuration. 3. Compare the two responses. 4. Conduct literature review and compare your proposed system with the state-of-the-art technology.

Design Questions Requirement 1) Implement a timer with the use of a binary up counter driven by a 1 Hz clock. The timer is activated for a duration of 10 seconds. After 10 seconds has elapsed, it should provide an output signal to the vehicle counter to request it to stop the vehicle counting process. Show the timing diagram in order to verify that it is counting up correctly.
Subject: Digital Logic Design Missile Launch Control System.You are required to design a missile launch control system. Your system must decide whether to fire a missile or not based on three inputs: • Target distance, D. • Missile type, M. • Aggression level, A. Target distance can be of two types, Near (1) and Far (0). Missile type can be either Short Range (1) or Long Range (0) and Aggression level can be either Enemy (0) or Friendly (1). Following are the system constraints:• A short-range missile can only hit Near targets, it cannot hit Far targets. • A long-range missile can hit both Near and Far targets. • You must not fire at a Friendly target. • The output of the system is Fire, F (F=1 (Fire Missile), F = 0 (Do not fire)). You are required to provide the following: 1) Truth table for F 2) Algebraically simplified expression for F in Product of sum (POS) form. 3) A circuit diagram for F of POS form. 4) Algebraically simplified expression for F′ in sum of products (SOP) form. 5)…

Question#5 In a certain chemical-processing plant, a liquid chemical is used in a manufacturing process. The chemical is stored in three different tanks. A level sensor in each tank produces a HIGH voltage when the level of chemical in the tank drops below a specified point. Design a circuit that monitors the chemical level in each tank and indicates when the level in any two of the tanks drops below the specified point. [5 Marks]
6. Given a unidirectional controller for a sanitizer booth. It has 2 doors, a button for entrance and a pressure sensor to spray the sanitizer. Assume each operation takes one clock cycle. i. The booth should do nothing until it receives its inputs. ii. If a person presses the button, the entrance door 1, D1 should open to admit the person and then close again. iii.If a person is detected in the booth, the spray will go on. Otherwise, the booth should do nothing. iv. Once the sanitizing is finished, the second door, D2 should be opened. v. Once the person has left, the door D2 should close again. Construct a finite state machine that models this sanitizer booth.
