Consider the seven-segment display shown in Figure 2.20 on page 65. Each segment is a light emitting diode that is turned on (gives out light) if a logical 1 is given as input to the driver circuit of the LED. Typically, a logical circuit converts a 4-bit BCD number to display digits 0 through 9. Assume that the LED d is on to display digit 9. You can assume that inputs 10 through 15 are not given to the circuit. (a) Give the truth table for the logical circuit that drives LED d. (b) Implement your truth table in part (a) using a single 8-to-1 multiplexer. Your solution should not use any additional logic gates.
