Excess-3 Code and its Conversion

Posted on March 15, 2023June 19, 2025 By vlsifacts No Comments on Excess-3 Code and its Conversion

Excess-3 code is a BCD code. It is a self-complementing code, but not a weighted code. In earlier articles, we have seen decimal to binary conversion, decimal to 8421 BCD conversion and vice versa. In this article, we will learn about Excess-3 code and its conversion. Excess-3, as its name says, there is an excess…

What are the Different Types of BCD Codes

Posted on March 14, 2023June 19, 2025 By vlsifacts No Comments on What are the Different Types of BCD Codes

There are different types of BCD codes; however, the 8421 code is the most popular one. In this article, we will highlight three different types of BCD codes, such as 8421, 2421, and Excess-3. Both 8421 and 2421 are weighted code, whereas Excess-3 is not weighted. The above table shows the binary code groups for…
