It is necessary to design a decimal Adder for two digits represented in Excess-3 code. Show that the correction after adding the two digits with a four-bit binary adder is as follows. The output carry is equal to the carry from the binary adder. If the Output carry is 1 ... add 0011. if the output carry is 0 then add 1101. construct a four-bit decimal adder using two 4-bit adders and an inverter..
