An ABCD-to-seven-segment decoder is a combinational circuit that converts a decimal digit in BCD to an appropriate code for the selection af segments in an indicator used to display the decimal digit in a familiar form The seven outputs of the decoder (a, a a de,t g select the corresponding segments in the display, as shown below. The numeric display chosen to represent the decimal digit is shown below. Using a truth table and Kamaugh maps (for segments g and donly), design the BCD-to-seven-segment decoder (for upside down display as shown below) using a minimum number of gates.
