Data errors in a digital system can happen due to faults in the transceiver system or noise during the transmission. Such errors need to be detected and corrected, as digital systems are sensitive to such errors. The presence of data errors beyond a threshold can lead to catastrophic situations if not taken care of immediately….
Gray code is considered beneficial for multiple electromechanical applications due to its error resilience property. This is achieved due to the single-bit change from one code word to the adjacent next code word. This article lists down a few more applications of Gray code. Reference: Maini, Anil K. Digital electronics: principles, devices and applications. John…
In this article, we will learn about the conversion of binary to Gray code and vice versa. You can refer to the gray code table, where we have already shown the gray codes of 3-bit numbers, that is, the decimal numbers from 0 to 7. In this article, we will learn the conversion techniques so…
Gray code is beneficial for multiple electromechanical applications of digital systems, such as shaft position encoders, autonomous braking systems, copiers etc. In all these applications, an input sensor produces a digital value that indicates a mechanical position. When continuous or analog information is converted to digital form, as in the case of the above applications,…

Gray code is a digital code, which is neither arithmetic nor weighted. There are no weights assigned to the bit positions of a Gray code. Moreover, we do not use Gray code for arithmetic operations. The advantage of Gray code is that it is very less error susceptible while encoding data compared to the straight…
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…
BCD numbers are numerical numbers. So, arithmetic operations can be performed on BCD numbers. Imagine a seven-segment timer display system showing 2 digits for the count of seconds. After every second, the timer should be incremented by 1. This means that the timer display system requires a BCD adder at the backend, whose output is…
Earlier, we learned that BCD code and the binary equivalent of a decimal number are different. In this article, we will learn that how to convert binary to BCD and vice versa. To convert binary to BCD, we will first convert the binary number to decimal and then the decimal number to BCD number. Similarly,…

In one of the previous articles, we learned about Binary Coded Decimal (BCD) numbers. In this article, we will learn about how to convert a Decimal number to a BCD number and vice versa. Decimal number to BCD number Conversion To convert a decimal number to the BCD number, we need to replace every digit…

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…
