Give a circuit diagram that takes four inputs B1,B2,B3 and B4 and one output O where B4B3B2B1 forms the binary representation of a number X between 0 and 9 inclusive, and O is 1 precisely when the segment labelled G in the 7segment display to the right should be on when representing the digit X. Use Karnaugh maps to keep the number of gates in your circuit low. Give a circuit diagram that takes four inputs B1,B2,B3 and B4 and one output O where B4B3B2B1 forms the binary representation of a number X between 0 and 9 inclusive, and O is 1 precisely when the segment labelled E in the 7segment display to the right should be on when representing the digit X. Your circuit should use only NAND, NOR and inverter gates, and furthermore, it should use as few gates as possible to implement the stated functionality
