Answer / golshan

It is possible to build adder using decoders
But full adder has 3 inputs so you should be basically
using 3:8 decoder

The logic is simple for full adder there are 2 outputs -
Sum and carry
Now use the input of Full adder A B and C (previous carry)
as input to the decoder
Depending on the state of inputs the output line will be
either 0 or 1
now use a OR gate and OR the lines which have 1 output
during the desired state of inputs
apply the same for carry too

Answer / vivek

solution given by gulshan is correct

Answer / raghava

it should consist equal ratio,because the adder send 3 and
decoder gets 8 its not possible to increase the level.
so no solution according to this quetion.
