4.1 Consider the combinational circuit shown in Fig P4.1 T. F, FIGURE P4. (a) Derive the Boolean expressions for Ti through T. Evaluate the outputs Fi and F (b) List the truth table with 16 binary combinations of the four input variables Then list (c) Plot the output Boolcan funetions obtained in part (b) on maps and show that the as a function of the four inputs the binary values for T, through T4 and outputs Fi and F in the table simplified Boolean expressions are equivalent to the ones obtained in part (a)
