Design a combinational circuit that maps a 4-bit binary coded decimal digit to the signals that control a seven-segment display. The display element contains seven light-emitting diodes (LEDs). If the appropriate LED control line is asserted, the associated LED segment lights. Assume that the LED lights when its input is high. If the input is low, the LED segment is off. The seven segments are controlled independently. Figure 1 shows the seven-segment display and configurations for displaying ea
