SOLVED: The table below shows the decimal representation of the Gray code. From this table, design an encoder that transforms this code into a common 4-bit binary system. Then place in the Karnaugh diagram the possibility assumed by the input variables of the Gray code. Get the simplified expressions and build the combinational logic circuit.
