A circuit with two outputs has to implement the following functionsf (x1, x2, x3, x4) = m(0,2, 4, 7, 9) + D(6, 10, 11) g(x1, x2, x3, x4) = m(0, 2, 4, 9, 10,15) + D(13, 14) Design the multiple-output minimum-cost circuit and compare its cost with combined costs of two circuits that implement f and g separately. Assume that the input variables are available in both un-complemented and complemented forms. Also assume n-input gates are available (2-input, 3- input. n- input).
