BCD code isn't valid for these integers , 10 , 11 , 12 , 13 , 14
i.e if these integers ae converted to binary code they 'd be called wrong BCD
advantages of bcd codes:-- it combine all basic numbers- it is easilly understand by human beings

The name BCD doesn't stand for anything according to Bernd Rittinger, BCD Travel Director of Operations.

Explain how an integer can be represented using BCD?
detects the invalid portion of the bcd number codes (1010-1111)
A 4 BCD code is a 4 decimal-digit BCD code, thus a 16 digit binary-code. You take the decimal number 3545. It's BCD code is 0011 0101 0100 0101 where every 4 bits represent a decimal digit.
BCD-BinaryCodedDecimal->Binary equivalent of each decimalexpressed using 4 bits->For single digit decimal BCD is same as its binary.In BCD only first 10 binary numbers are valid.The remaining 5 are invalid. Gray code is an unweighed code. ex: G3=B3 G2=G3 XOR B2 G1=G2 XOR B1 G0=G1 XOR B0

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.

I will answer this by example: BCD is unweighted code, XS3 is weighted by 3 code. 0 in BCD 0000, XS3 0011 1 in BCD 0001, XS3 0100 2 in BCD 0010, XS3 0101 3 in BCD 0011, XS3 0110 4 in BCD 0100, XS3 0111 5 in BCD 0101, XS3 1000 6 in BCD 0110, XS3 1001 7 in BCD 0111, XS3 1010 8 in BCD 1000, XS3 1011 9 in BCD 1001, XS3 1100
Design a BCD to Excess-5 code coverter
4 full adders will be used BCD is a 4 bit code. Each bit of the BCD number will be an input of each full adder. input 1 in first FA. 1 in second and 0 in the last to FA's
we converter BCD to EXCeSS-3 is first rule 2 4 2 1 and other third number of BCD add other BCd as 0 to 15 Type your answer here...

Either buy a 4 bit BCD counter chip, or strap a 4 bit ripple counter chip into BCD mode, or build 4 Eccles-Jordan flipflops, hook them up as a ripple counter, and strap it into BCD mode.
