If you don't know the correct solution to the problem, please don't take the question. If possible, write the solution on paper. Thank you in advance.

Q2. (25 points) Consider the logic unit M shown below (Figure 2.1), where a,b,c,d and e are the inputs; y is the output with the functional description given in the below truth table (Table 2.1). You are required to design logic unit M by using only a minimum number of 2:4 decoders (Figure 2.3). Complements of the variables are not available. Logic levels 1 and 0 are available. Show your design clearly. You will lose points for sloppy and illegible drawings. Table 2.1: Truth Table for Logic Unit M
