The BCD stands for Binary Coded Decimal Number. In BCD code, each digit of the decimal number is represented as its equivalent binary number.
...
Example 1: (11110) 2.
| Binary Code | Decimal Number | BCD Code |
|---|---|---|
| 0 1 1 1 | 7 | 0 : 0 1 1 1 |
| 1 0 0 0 | 8 | 0 : 1 0 0 0 |
| 1 0 0 1 | 9 | 0 : 1 0 0 1 |
| 1 0 1 0 | 10 | 1 : 0 0 0 0 |

Is BCD and binary same?
In BCD we can use the binary number from 0000-1001 only, which are the decimal equivalent from 0-9 respectively. ... This is the main difference between Binary number and binary coded decimal. For 0 to 9 decimal numbers both binary and BCD is equal but when decimal number is more than one bit BCD differs from binary.
Is BCD a binary or decimal?
In computing and electronic systems, binary-coded decimal (BCD) is a class of binary encodings of decimal numbers where each digit is represented by a fixed number of bits, usually four or eight. Sometimes, special bit patterns are used for a sign or other indications (e.g. error or overflow).
What is the 8421 code?
In other words, the BCD is a weighted code and the weights used in binary coded decimal code are 8, 4, 2, 1, commonly called the 8421 code as it forms the 4-bit binary representation of the relevant decimal digit.
What is a BCD number?
(Binary Coded Decimal) The storage of numbers in which each decimal digit is converted into a binary number and stored in a single 8-bit byte. For example, a 12-digit decimal number would be represented as 12 bytes. BCD uses more storage for numbers than binary encoding (see below).
What is the BCD code of 89?
Therefore, the binary equivalent of decimal number 89 is 1011001.
What would be the BCD equivalent of decimal 27 in 16 bit representation?
The BCD equivalent of 27 in 16-bit representation = 0000000000100111.
How do you write code 8421?
8421 code A weighted code in which each decimal digit 0 through 9 is represented by a four-bit codeword. The bit positions in each codeword are assigned weights, from left to right, of 8, 4, 2, and 1.
What is BCD to decimal decoder?
CD4028 - BCD-to-Decimal Decoder. The CD4028 is a BCD-to-decimal or binary-to-octal decoder consisting of 4 inputs, decoding logic gates, and 10 output buffers. A BCD code applied to the 4 inputs, A, B, C, and D, results in a high level at the selected 1-of-10 decimal decoded outputs.
Why BCD is called 8421?
The BCD8421 code is so called because each of the four bits is given a 'weighting' according to its column value in the binary system. The least significant bit (lsb) has the weight or value 1, the next bit, going left, the value 2. ... 2410 in 8 bit binary would be 00011000 but in BCD8421 is 0010 0100.
What is 2421 BCD code?
The Aiken code (also known as 2421 code) is a complementary binary-coded decimal (BCD) code. A group of four bits is assigned to the decimal digits from 0 to 9 according to the following table.
