Seven-segment displays are commonly used in calculators to display each decimal digit. Each segment of a digit is controlled separately, and when all seven of the segments are on, the number 8 is displayed. The upper right segment of the display comes on when displaying the numbers 0, 1, 2, 3, 4, 7, 8, and 9. (The numerical designation for each of the digits 0 to 9 is shown in Figure P5-40 and described in more detail in Section 12-6.) Design a circuit that outputs a HIGH (1) whenever a 4-bit BCD code translates to a number that uses the upper right segment. Use variable A to represent the 23 BCD input. Implement your design with an AOI and inverters.
