Question 44577

Logic Circuits/Vlsi

Problem 5: (10 pts) The security alarm system you designed in Problem 4 has an issue that it accidentally gets triggered by pets. You consider improving the system by triggering an alarm only if at least two motion sensors are activated at the same time. Show a truth table that has the four motion sensors as inputs and an alarm trigger as the output which shows how to implement the improved security system design.

Question 44576

Logic Circuits/Vlsi

Problem 4: (10 pts) You are asked to build a digital logic circuit for a security alarm system. The system has four Motion Sensors which indicate the presence of an intruder. Each individual motion sensor should be able to trigger an alarm. The system should be completely disabled via a Master Switch. In addition, the siren, the flashlight and the automated call to the security should have separate enable switches. The inputs and outputs are specified as follows:company
