A car seat belt interlock requires that the car should only start if the driver's seat belt is fastened and either the front passenger seat is unoccupied or the front passenger seat is occupied and the passenger seat belt is fastened. In order to design the system, sensors have been attached to the each of the inputs of your system for detection purposes. Consider the car start switch as output Y, sensor in the driver seat belt as input A, sensor in the front passenger seat as B and sensor in the passenger seat belt as input C. Construct a truth table for the system and find the simplified output SOP expression and design the system using basic logic gate. (Non-anonymous questionO)

Design a security system for a smart home that includes a door and a window sensor. The system should trigger an alarm when a door or the window is opened while the security system is active. Your task is to design an ASIC based system that efficiently monitors the state of the door and window sensors and activates the alarm when necessary. You should consider inputs for the security system state (activated, deactivated) and the open/closed state of each sensor for door and window, and the output for the alarm activation. a) Provide gate level implementation with minimum possible number of gates. Use standard minimization techniques used in digital design to reduce the gates count. b) Develop the most efficient SCMOS transistor switch level schematic for the minimized logic obtained from part A. c) Develop the most efficient stick diagram for the layout in part B, and estimate the area in micron square d) Develop Standard cell layout and find the density of the logic e) Produce routing…

8. What instruction would you select for each of the following discrete input field devices to accomplish the desired task? (State the reason for your answer.) a. Turn on a light when a conveyor motor is running in reverse. The input field device is a set of con- tacts on the conveyor start relay that close when the motor is running forward and open when it is running in reverse. b. When a pushbutton is pressed, it operates a so- lenoid. The input field device is a normally open pushbutton. c. Stop a motor from running when a pushbutton is pressed. The input field device is a normally closed pushbutton. d. When a limit switch is closed, it triggers an instruc- tion ON. The input field device is a limit switch that stores a 1 in a data table bit when closed.

PWM is the method that; 1. Sends an encrypted message. 2. Brakes a motor. 3. Creates an equivalent analog effect from digital pulses. 4. Creates an equivalent digital effect from analog pulses. 5. Runs a motor in forward and backward.

Q.1) Assume that the control of a bottle filling system is performed with an 8051 microcontroller. • The start and stop of the conveyor is controlled by the P1.0 pin. • The bottles are moving on the conveyor and detected with a sensor. When they arrive at the filling place, they are detected with a logical "1" signal, otherwise they are detected with a "0" signal. • A valve connected to P1.1 turns on for 10 seconds to fill each bottle. • At every X bottles, the conveyor will stop for 8 minutes and then start again. The remaining time to restart in the waiting period is displayed in minutes on the 7-segment display. • Logic "1" is detected from P1.3 during the operation of the system. Logic '0' is detected from P1.3 at the end of the shift. • At the end of the shift, the number of the filled bottles will be determined and saved in a memory location as 2 bytes. Write the required program. (Crystal Frequency:12MHZ). NOTE: X number will be taken as the last 2 digits of 59
