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 then 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..
