The BIOS in many personal computers stores the date and time in BCD because the MC6818 real-time clock chip used in the original IBM PC AT motherboard provided the time encoded in BCD. This form is easily converted into ASCII for display.[4]
The Atari 8-bit family of computers used BCD to implement floating-point algorithms. The MOS 6502 processor used has a BCD mode that affects the addition and subtraction instructions.
Early models of the PlayStation 3 store the date and time in BCD. This led to a worldwide outage of the console on 1st march 2010. The last two digits of the year stored as BCD were misinterpreted as 16 causing a paradox in the unit's date, rendering most functionalities inoperable

What is the difference between weighted and non weighted codes?
what is weighted codes: The decimal value of a code is obtained summing up the positional values. weghted binary code s are those which obey positional weighting principle. each position of number represents a specific weight. There are millions of weighted code The most common one is 8421 Non weighted codes: This codes are not positionaly weghted. each position with in the binary no is not assgned to afixed value.Examples of nonweghted code is ASCCI, GREY CODE, EBCDIC CODE etc
BCD to Gray Code Converter?
BCD refers to Binary Code Decimal there are no diagrams it is just a numbers system GRAY code is a means to make one reliable state to change at a time eliminating false coding because of transitions in counters and such

What is a 4 BCD code?
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.
What are the 4 an invalid BCD code?
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
What does a BCD invalid code detector do?
detects the invalid portion of the bcd number codes (1010-1111)
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.

10 in BCD code is representd as?
The decimal number 10, represented in BCD is 0001 0000. If, instead, you mean that you have 10 in BCD and want to know what that means, that is equivalent to 0000 0010 and would be 2 in decimal.
Construct BCD to excess3 code using full adder circuit?
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
What is bcd to gray code converter?
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
