4.18 Design a combinational circuit that generates the 9's complement of a (a) BCD digit. 4.4 Design a combinational circuit with three inputs and one output. (a) The output is 1 when the binary value of the inputs is less than 3. The output is otherwise. (b) The output is 1 when the binary value of the inputs is an even number. 4.5 Design a combinational circuit with three inputs, x, y, and z, and three outputs, A, B, and C. When the binary input is 0, 1, 2 or 3, the binary output is one greater than the input. When the binary input is 4,5,6, or 7, the binary output is two less than the input. 4.24 Design a BCD-to-decimal decoder using the unused combinations of the BCD code as don't care conditions. 4.28 Using a decoder and external gates, design the combinational circui defined by the following three Boolean functions: (a) Fi = x'yz' + x2 (b) F, = (y + x)2 F2 = xy'z' + x'y F2 = y'z' + xy + yz' F3 = x'y'z' + xy F3 = (x + y)2
