BCD Codes:
BCD stands for Binary Coded Decimal.
In BCD, each decimal digit is encoded by a group of the 4-bit binary number,
There are various types of BCD codes like 8421, 2421, 5421, 84-2-1 etc. But 8421 BCD code is one of the widely used BCD codes.
Excess-3 Code:
XS-3 is Non-weighted, Self complementing BCD code. It is also sequential code. By adding 3 (0011) to each BCD code, it can be converted into the equivalent XS-3 code.
In this video, various BCD codes are explained and the different code conversions like Binary to BCD, Hexadecimal to BCD, Octal to BCD are explained with examples.

Octal to binary conversion at 6:03 is not correct it should be 110010001... ; please check it once

Its not octal to binary, its octal to BCD conversion. What you are saying is octal to binary conversion.

How to find BCD code of letter "BASE"

@Shiva671 Жыл бұрын

Hello Here in 2421 BCD , BCD of 5 is 1011 but it is also 0101 so which one is right ?🤔

@ALLABOUTELECTRONICS Жыл бұрын

The code is assigned such that, the number 5 to 9 are mirror image of 0 to 4. (Replace 1s by 0s and 0s by 1) Also, it is a self complementing code. Meaning that, you can find the 9s complement of the number by replacing 0s by 1s and 1s by 0s. I hope, it will clear your doubt.

No just write without base.

What is the value of F here? generally how we can find the alphabets values?

@ALLABOUTELECTRONICS Жыл бұрын

F is typically used in Hexadecimal number system. I assume you are asking, the corresponding BCD code for F. So, F in decimal is equivalent to 15. So, in BCD format, we will have two digits (1 and 5). so, we need to represent each digit in 4-bit BCD form. Therefore, F in hexadecimal is equivalent to 0001 0101 in BCD. Similarly, if one wants to represent A (which is 10 in decimal), then it is equivalent to 0001 0000. I hope, it will clear your doubt.

in 8 4 -2 -1 and 2 4 2 1 BCD codes, I noticed that some decimal numbers can be represented in more than 1 way. So, can I represent them in any way ? or the way as shown in the video ?

@ALLABOUTELECTRONICS 6 ай бұрын

2421 and 84-2-1 are self-complementing codes. That means you can find the 9s complement of the number just by replacing the 1s by 0s and 0s by 1s. For example, the 9s complement of the number 4 is 5 (9-5). So, in these codes, if you see the code of digit 5, then you can find that code by replacing 1s by 0s and 0s by 1s in the code of 4. And the weights are assigned accordingly. That means although it is possible to represent the number in multiple ways, we should use only that code, where the above condition (self-complementing) condition gets satisfied. I have also covered one example based on that recently on the second channel. Please go through it, you will get it. Here is the link: kzfaq.info/get/bejne/h91khK6H25qzhac.htmlsi=b_AZA1WLvnYXCVub

5C is in hexadecimal. If you convert it into decimal then it is 92. (5*16 + 12*1 = 92). Please check it once again, you will get it.

Sir in 6:03 why you took 4 bits for octal it supposed to be 3?

@ALLABOUTELECTRONICS 2 жыл бұрын

4 bits are for BCD. Here, first octal number is converted into decimal. And then each decimal digital is represented into equivalent BCD representation using 4 bits. Please watch that portion once again, it will get clear to you.
