An ABCD-to-seven-segment decoder is a combinational circuit that converts a decimal digit in BCD to an appropriate code for the selection of segments in an indicator used to display the decimal digit in a familiar form. The seven outputs of the decoder (a, b, c, d, e, f, g) select the corresponding segments in the display, as shown in Fig (a). The numeric display chosen to represent the decimal digit is shown in Fig (b). Using a truth table and Karnaugh maps, design the BCD-to-seven-segment decoder using a minimum number of gates.

Question
**ABCD-to-Seven-Segment Decoder Overview** An ABCD-to-seven-segment decoder is a combinational circuit that converts a decimal digit in Binary-Coded Decimal (BCD) to an appropriate code for segment selection in an indicator. This indicator is used to display the decimal digit in a familiar form on digital displays. The decoder outputs (labeled a, b, c, d, e, f, g) select the corresponding segments for display, as illustrated in Figure (a). The numeric display format, which represents the decimal digit, is shown in Figure (b). **Design and Implementation** To design the BCD-to-seven-segment decoder efficiently, use a truth table and Karnaugh maps to minimize the number of logic gates required. Ensure that the six invalid BCD combinations result in a blank display to prevent erroneous outputs. **Figures Description** - **Figure (a): Segment Designation** This figure provides a schematic of the seven segments (a-g) that form a digital number on the display. Each segment can be independently controlled to form different numbers. - **Figure (b): Numerical Designation for Display** Displays numbers 0 to 9 using the seven segment configuration. Each number is constructed by lighting the appropriate segments as determined by the decoder outputs. **Design Note** Please be aware that this design approach is distinct from the one discussed in the lecture. **Exercise** 1. Using a Karnaugh map, derive a minimum sum-of-products form for each segment. This educational content is intended to enhance your understanding of combinational circuits and their application in digital displays.
