Why can't 1111 be used in a BCD number?
1111 can't be used for Binary Coded Decimal (BCD) because 1111=15 which is made of 2 digits 1 and 5. In BCD a 4-digit binary number is used for every decimal digit. ex. 1111 is incorrect 1 = 0001 5 = 0101 Answer: 0001 0101
What is a number system in which each decimal digit is coded individually into binary?
BCD, which stands for Binary Coded Decimal. 4 bits are used to code each decimal digit. So we have 0000 for zero, up to 0111 for seven, then 1000 for eight and 1001 for nine. The others {ten through fifteen} are not used, as those numbers are formed from additional decimal digits. So if you wanted to form twelve, in BCD it is 0001 0010, for 12{base ten}
How does BCD differ from the straight binary number system?
To consider the difference between straight binary and BCD, the binary numbers need to be split up into 4 binary digits (bits) starting from the units. In 4 bits there are 16 possible values from 0000 to 1111 (0 to 15). In straight binary all of these possible combinations are used, thus: 4 bits can represent the decimal numbers 0-15 8 bits can represent the decimal numbers 0-255 12 bits can represent the decimal numbers 0-4095 16 bits can represent the decimal numbers 0-65535 etc In arithmetic, all combinations of bits are used, thus: 0000 1001 + 0001 = 0000 1010 In BCD or Binary Coded Decimal, only the representations of the decimal numbers 0-9 are used (that is 0000 to 1001 in binary), and the 4-bits (nybbles) are read as decimal digits, thus: 4 bits can represent the decimal digits 0-9 8 bits can represent the decimal digits 0-99 12 bits can represent the decimal digits 0-999 16 bits can represent the decimal digits 0-9999 In arithmetic, only the representations of decimal numbers are used, thus: 0000 1001 + 0001 = 0001 0000 When BCD is used each half of a byte is read directly as a decimal digit. BCD is obviously inefficient as storage (for large numbers) as each nybble is only holding 3/8 of the possible numbers, however, it is sometimes easier and quicker to work with decimal digits (for example when there is lots of display of counting numbers to do there is less binary to decimal conversion needing to be done).
Why in bcd to excess 3 conversion binary valus are taken up to 9 only?
because 9 is a lucky number for bcd..............ha ha ha
What is packed decimal in cobol?
In Cobol, they had a serious concern for memory size. So they came up with a method known as BCD (Binary Coded Decimal), where a decimal value was converted to binary to save space. Check this link out. It will break down the details.
represent decimal number 862 a) BCD?
BCD of 862 is 100001100010
What is the BCD representation of the decimal number 41 in 6-bit?
41 in decimal is 0100 0001 in BCD (this is 8 bits not 6 bits)41 in decimal is 101001 in binary (this is 6 bits, but binary not BCD)There is no 6 bit BCD representation of the decimal number 41!
Why is BCD used in computers?
BCD is used for binary output on devices that only display decimal numbers.
The BCD value for the decimal number 82 is?
11010010
What is the difference between binary codes and bcd codes?
In BCD each digit of a decimal number is coded as a separate 4 bit binary number between 0 and 9.For example:Decimal 12 in BCD is shown as 0001 0010 (Binary 1 and Binary 2), in Binary it is 1100.
How do you convert BCD to decimal?
explain decimal to BCD encoder

What is the difference between a BCD to decimal decoder and a BCD to 7-segment decoder?
A: A BCD code must be decoded to provide a seven digit output to the 7 bars display that is the only way to see the binary number visually.
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.
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.
What is the BCD equivalent for a decimal number 163?
It is 0001 0110 0011.
What is the Largest decimal number that can be represented using 16 bits in BCD?
65,535
