Circuit 5: Design a circuit given a word specification. A chemical process is monitored by three digital sensors: Temperature (x), pressure (y), and heater power ( z ). If temperature is at or below normal, x is 0 ; if it is high, it is 1 . If pressure is normal or below, y is 0 ; if it is high, y=1. Heater power off corresponds to z=0; heater power on corresponds to z=1. There are two dangerous conditions: (1) Temperature (x) and pressure (y) high and heater power (z) on (which will lead to higher temperature and pressure and could cause an explosion), and (2) temperature (x) and pressure (y) normal but power (z) off (which means that the process may be approaching too low an operating point, and thus ruin the batch of chemicals in process). Design a circuit with inputs x,y,z and outputs L1,L2. If condition (1) exists, yourcircuit must generate an output L1=1 to turn on LED 1. If condition (2) exists, the circuit must generate an output L2=1 to turn on LED 2. L1 and L2 are 0 for all other input combinations. First, fill the truth table below based on the specifications.
