4.37 A combinational circuil has four inputs (A,B,C,D), which represent a binarycoded-decimal digit. The circuit has two groups of four oulpuls-S,T,U,V, and W,x,Y,Z. Each group represents a BCD digit. The oulpul digils represent a decimal number which is live limes the input number. For example, if ABCD=0111, the outputs are 0011010)1. Assume that invalid BCD digits do not occur as inputs.
(a) Construct the truth table.
(b) Write down the minimum expressions for the outpuls by inspection of the truth table. (IIint: Try to match oulput columns in the table with input columns.)
