A seven-segment display is a device composed of 7 elements, as shown in the figure below. Each element is selectively lit to form patterns such as numbers or letters. For example, to display '0', the segments A, B, C, D, E and F have to be simultaneously lit. A circuit decoder takes in a 4-bit binary number and produces the outputs A, B, C, D, E, F and G. The outputs of the decoder are then fed to the seven-segment display as shown in the figure. The seven-segment display should show the sum of the 4-bit input + 1. For example, if the 4-bit input is 000 , the decoder’s output will lit up the seven-segment display that will show the numerical number 1. This corresponds to the decoder output of 01100002. In the case wherein the 4-bit input = 1001 , the decoder’s output will lit up the seven-segment display that will show the numerical number 0. This corresponds to the decoder output of 1111110 . The decoder’s output line should be logic “1” if the segment will be lit and “0” otherwise.…
