Last Revised: 9/8/2009 1 EE 101 Lab 1 Sound the Alarm 1 Introduction In this lab you will design, implement and then test a simple logic circuit emulating a home alarm system. You will use the Digital Trainer board for this lab. 2 What you will learn This lab is intended to teach you the basics of building and wiring digital circuits. You will also be asked to think of a test strategy to ensure your circuit works as specified in the following English-language description. 3 Background Information and Notes The Alarm System : The alarm system to be designed has the following inputs. Input Description N The system enable (i.e. the on/off state of the alarm system). 1 = Enabled / 0 = Disabled) W Window sensors = 1 indicates all windows are secured/closed D Door sensors = 1 indicates all doors are secured/closed G Garage sensor = 1 indicates the garage door is secure X Exiting input. 1 indicates that you are currently leaving the house and thus an open door or window should not cause the alarm to turn on. 0 indicates that you are out of the house. The only output of the alarm system should be a single bit, A, which will be 1 if the alarm is activated and 0 otherwise. The alarm should activate if the system is enabled, you are not exiting, and the house is not secure. The house is considered secure if all the sensors (windows, doors, garage) are 1.
