Here we will try to understand Binary Codes and its Classification.
Binary Codes and its Classification:
The binary codes are classified into two categories.
1. Numeric Codes
2. Alpha Numeric Codes
In our course, we deal with numeric codes.
The clear classification of the binary codes is as shown in the image below.
The binary codes are classified into two.
1. Numeric Codes
2. Alpha Numeric Codes
Numeric Codes:
Numeric codes are used to represent the Decimal Digits ( Which are called Binary Coded Decimal Digits BCD Codes ).
Every decimal digit { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 } is uniquely coded.
It is another way to convert binary numbers to decimal numbers.
In the previous discussion, we have discussed How to convert Decimal Number to Binary Number.
How a Decimal Number is represented in BCD Numbering System?
A decimal number is separated into four bits for each decimal digit within a decimal number.
One way is the weighted binary value direct translation.
For example, consider the decimal number (357)10 and represent this number in binary and BCD Numbering System.
( 357 )10 in the Binary Numbering system is as shown in the image below.
The above conversion is based on Double Dabble Method.
( 357 )10 in BCD Numbering System is as shown in the image below.
The above is the BCD way of conversion where every decimal digit is represented in its true binary translation.
Do we have applications of BCD representations in Engineering?
Yes Very few.
1. Digital Display.
2. BCD approximates floating points in an efficient way.
Digital Display:
The display in the digital clocks is based on BCD codes we call it a seven-segment display.
The image of the seven segment display is as shown in the image below.
Every decimal number can be digitally represented by the above 7-segment display.
BCD approximates floating points in an efficient way:
The other use of the BCD numbering system is the approximations of floating-point numbers.
Which is still used by many banking systems.
For example, consider the amount 356.2.
How 0.2 is represented in the binary number system?
0.2 in binary is 0.00110.....
It will never end, where we have to take the approximations.
This is not a good practice in the case of money.
But by the use of the BCD numbering system, we can approximate the floating-point numbers finitely.
0.2 is represented as 0.0010 in BCD Representation.
Alpha Numeric Codes:
Used to represent Alpha Numeric Information.
This is a coding mechanism to represent the alphabets, special characters, and numeric values in the keyboard.
ASCII and EBCDIC are the two standards widely used.
