Design a BCD-to-decimal decoder using the unused combinations of the BCD code as don't-care conditions. A combinational circuit is defined by the following three Boolean functions. Design the circuit with a decoder and external gates. \[ \begin{array}{l} F_{1}=x^{\prime} y^{\prime} z^{\prime}+x z \\ F_{2}=x y^{\prime} z^{\prime}+x^{\prime} y \\ F_{3}=x^{\prime} y^{\prime} z+x y \end{array} \]
