2. you are designing a bcd to excess 3 code converter for a single bcd digit. for the level 0 diagram, how many inputs and outputs should the block have?

a. 4 inputs corresponding to the bcd and 4 outputs corresponding to the excess 3 code 1011 1011

b. 1 input corresponding to the bcd and 1 outputs corresponding to the excess 3 code

c. 2 inputs corresponding to the bcd and 2 outputs corresponding to the excess 3 code

d. 3 inputs corresponding to the bcd and 3 outputs corresponding to the excess 3 code
