You are asked to design a digital display for a thermometer in an air

conditioner, which displays the room's temperature on an eight$-$level LED

bar display. Each LED segment of the bar is illuminated when logic level

$\text{'}1\text{'}$ is given to that segment. The digital circuit should accept a number

between $0-7($including $0$ and $7)$ and illuminate the correct segments of

the bar display. The room's temperature can be between $0-32C.$

Draw a table showing the temperature ranges and the numbers you use

to represent each temperature range.

Draw a truth table to show the input$($s$)$ to the circuit and the outputs to

each LED bar segment.

Implement this function using a Programmable Logic Array of appropriate

size.
