Task $2-$ Logic circuits

We want you to make a logic circuit similar to the ones we have done in class. To make sure you all

have a different problem, we will use your student code to generate the problem. Your student code

has eight digits. For example:

$20016432$

Each digit is a number from $0$ to $9.$

Some digits are in your student code and some are not. For example, in the code above, the digit $"6"$

is in the student code, but the digit $"8"$ is not.

Some digits are included more than once. For example, in the code above, the digit $"2"$ is used more

than once. The same applies to the digit $"0".$

One of the digits will be the largest digit in the code. In the example above, $"6"$ is the largest digit.

You are going to create a logic circuit using Digital Works that provides four switches so the user can

enter a number from $0$ to $15$ in binary. This number will be used to represent a possible value of a

decimal digit from $0$ to $9.($A four$-$digit binary number goes up to $15,$ of course. The numbers $10$ to $15$

or $1010$ to $1111$ in binary $-$ are not used.$)$

For example, the switches below represent the binary value $0110,$ or the digit $"6".$

You will connect these switches to a logic circuit using Digital Works. The circuit will light up one or

more LEDs, depending on the decimal equivalent of the binary value entered.

There are four LEDs, labelled as shown below.

Not included

Included.

More than onoe

$.$ Highest

If the digit IS NOT part of your student code, it will light up the "Not included" LED.

If the digit IS part of your student code, it will light up the "Included" LED.

If the digit is used MORE THAN ONCE in your student code, it will light up the "More than once" LED.

If the digit is the highest$-$value digit in your student code, it will light up the "Highest" LED.
