A limited company has four directors A, B, C, D holding 35%, 30%, 20% and 15% of the shares respectively. A major decision must have a support of minimum 60% of the stock. Design a combinational logic circuit for the voting in the company. Use a decoder to design the circuit. Show the truth table of the circuit.
1. Design a combinational logic circuit that will function as a building alarm device. Monitored are windows on the ground floor and an entry door. The system is designed so that an alarm is sounded in the event of infiltration of entry points by a stranger during the night time or anytime during weekends. Implement the circuit using logic gates.
Assume a three-story hospital is built at Expo Center Karachi, and you are hired to design the logic circuit for the newly installed lift. The lift only stops at Ground, Second, Third Floors. The lift has one button (RUN), that can be turned into Up or Down position. When the switch is turned to the UP position (i.e. R=1), the lift goes upward from the Ground floor (i.e. 0) to the top floor (i.e. 3), and if the switch is turned to the DOWN position (i.e. R=0) it will go downward. Design this synchronous sequential circuit for this up-down counter using the JK-flip- flops. Perform all design steps, including state-diagram, state-table, K-map, minimized expressions and finally, the draw the logic circuit.
a) Design a logic circuit with three inputs A, B, C and an output that goes LOW only when A is HIGH while B and C are different. Draw and upload the circuit if you can, or at least describe it in words. b) Which logic gates produce a 1 output in the disabled state? c) Which logic gates pass the inverse of the input signal when these gates are enabled? d) What is the normal resting state of the SET’ and RESET’ inputs of a latch circuit (the prime is same as bar)? What is the active state of each input? e) What is the normal resting state of the NOR latch inputs? What is the active state?

Represent the operation of the dispenser in logic circuit 4 get a logic circuit to mimic aorporate checquing system for operatore of a compnny
Many automobiles incorporate logic circuits toalert the driver to problems or potential problems. Inone particular car, a buzzer is sounded whenever theignition key is turned and either a door is open or a seatbelt is not fastened. The buzzer also sounds when thekey is not turned but the lights are on. In addition,the car will not start unless the key is in the ignition,the car is in park, and all doors are closed and seatbelts fastened. Design a logic circuit that takes all theinputs listed and sounds the buzzer and starts the carwhen appropriate.
Using Simple Logic Gates. Given: A Chemical plant needs a microprocessor-driven alarm system to warn of critical conditions in one of its chemical tanks. The tank has four (HIGH / LOW) switches that monitor: Temperature (T) Pressure (P) Fluid Level (L) Weight (W) To Find: Design a system that will notify the microprocessor to activate an alarm when any of the following conditions arise: High Fluid Level with High Temperature and High Pressure Low Fluid Level with High Temperature and High Weight Low Fluid Level with Low Temperature and High Pressure Low Fluid Level with High Temperature and Low Weight Note: Construct Truth Table. Draw Logic Diagram. Simplify Boolean equations using K-Map. Use Basic Logic Gates.
