Why is cin is grounded in BCD adder?

In a Binary-Coded Decimal (BCD) adder, the carry-in (cin) is grounded to ensure that the addition process starts without any initial carry from a previous operation. This is important because BCD addition requires special handling when the sum exceeds 9 (1001 in binary), necessitating an adjustment to maintain valid BCD representation. By grounding cin, the adder can accurately compute the sum of the two BCD digits, allowing for proper carry generation only based on the current addition.


Construct BCD to excess3 code using full adder circuit?

How i can Design a BCD-to-excess-3 code converter with a BCD-to-decimal decoder and four OR gates?

i dont know 1001+1001 - Constructing a BCD-to-excess-3-code converter with a 4-bitt adder we know that the excess-3 code digit is obtained by adding three to the corresponding BCD digit. To change the circuit to an excess-3-to-BCD-code converter we feed BCD-code to the 4-bit adder as the first operand. Then feed constant 3 as the second operand. The output is the corresponding excess-3 code. To make it a BCD to excess-3 converter, we feed the 2's complement of 3 as the second operand. - Constructing a BCD-to-excess-3-code converter with a 4-bitt adder we know that the excess-3 code digit is obtained by adding three to the corresponding BCD digit.
