Why we use BCD code in digital system?
The BCD system offers relative ease of conversion between machine-readable and human-readable numerals. In this article, we will learn about BCD, Binary Coded Decimal, which offers relative ease of conversion between machine-readable and human-readable numerals.
How many bits are needed to store one BCD digit a 2 bits B 3 bits C 4 bits D 1 bits?
A number with ‘n’ decimal digit will require 4k bits in BCD. Example: Decimal 396 is represented in BCD with 12 bits as 0011 1001 0110, with each group of 4 bits representing one decimal digit….4.6.
| Decimal Symbol | BCD Digit |
|---|---|
| 2 | 0010 |
| 3 | 0011 |
| 4 | 0100 |
| 5 | 0101 |
How many binary outputs would a three digit BCD to binary Converter have?
Explanation: The addition of ‘3’ to each digit yields the three new digits ‘8’, ’12’ and ’10’. Hence, the corresponding four-bit binary equivalents are 100011001010, in accordance to 8421 format.
How do I convert BCD?
There are the following steps to convert the binary number to BCD: First, we will convert the binary number into decimal. We will convert the decimal number into BCD….1) Convert BCD to Decimal.
| Steps | BCD Number | Conversion |
|---|---|---|
| Step 1 | (00101000)BCD | (0010)2 (1000)2 |
| Step 2 | (00101000)BCD | (2)10 (8)10 |
| Step 3 | (00101000)BCD | (28)10 |
How many bits are required to store a BCD digit?
In byte-oriented systems (i.e. most modern computers), the term unpacked BCD usually implies a full byte for each digit (often including a sign), whereas packed BCD typically encodes two digits within a single byte by taking advantage of the fact that four bits are enough to represent the range 0 to 9.
