Let's Program the Transistors
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…
You must have seen the digital clock in the railway station or at many other places. The hour, minute and second digits are seven-segment displays that deal with binary coded decimal (BCD) numbers. In this particular article, we will learn about the BCD code. BCD is a way to express each decimal digit in binary….
Binary coded decimal (BCD) is a way to express each of the decimal digits with a binary code. This means that each decimal digit, 0 through 9, is represented by a binary code of four bits. Eg: 98 => 10011000 Unpacking the BCD number is separating each BCD digit. Eg: 98 can be separated as 09…
