The figure shows the circuitry for a typical display consisting of 7 LEDs arranged in a figure of eight formation. The LEDs (labelled a to g) must be activated independently to make up the numbers 0 to 9. Because 9 is the highest number that can be displayed, the data driving each digit of the display is in the form of BCD, which restricts the range of the binary data to between 00002 and 10012. Note that it is the convention to list the BCD input columns A to D in reverse order, making A represent the least significant digit and D, the most significant digit. Develop a Truth Table to include all of the outputs for the seven-segment display (a to g) and use a K-map to design a logic circuit for the e output.
