Design an excess-3 code converter to drive a seven-segment indicator. The four inputs (A, B, C, D) to the converter circuit represent an excess-3 digit. Input combinations representing the numbers 0 through 9 should be displayed as decimal digits. The input combinations 0000, 0001, and 0010 should be interpreted as an error, and an "E" should be displayed. Assume that the input combinations 1101, 1110, and 1111 will never occur. Design your circuit using basic gates..
