6. Use 4 half-adders to design a four-bit combinational circuit increamenter (a 7. Draw the logic diagram of a combinational circuit that compares two four-bit numbers if they are equal. The circuit output is equal to 1 if the two numbers are equal and 0 otherwise. (hint: XOR or XNOR gate can be used to check if two bits are equal)
