Exercise 2:

The circuit below is a binary (DCBA) to Excess 3 XS3 (HGFE) decoder. Your task is to create a circuit that performs the same as this one and to test it exhaustively. In other words, there are 16 different combinations of inputs that need to be checked. In this exercise you will use gates (AND, OR) from the Logisim menu. You will need to develop a sense of tidiness again to be able to debug a faulty circuit path.

Testing:

To test this circuit, you should exhaustively try every possible input. Since this circuit is designed to convert a four-bit binary format to a different number system, only sixteen possible combinations exist. A recommendation for systematically testing your circuit is to start at '0' (0000) and count to '15' (1111). As you input each binary number, make a table as follows:
