Digital Electronics Lecture 3 | BCD, Excess-3 Code, Gray Code & Code Conversions

In this lecture, we will study BCD Code, Excess-3 Code, Gray Code and important code conversions in Digital Electronics. This lecture covers Decimal to BCD, BCD to Decimal, Decimal to Excess-3, Excess-3 to Decimal, Binary to Gray Code and Gray Code to Binary conversions with examples. These codes are very important in digital systems because they are used for decimal digit representation, error reduction, digital displays, counters, encoders, and position-based digital systems. Topics covered in this lecture: ✅ What are Binary Codes? ✅ Why binary codes are needed in Digital Electronics ✅ Weighted and Non-Weighted Codes ✅ 8421 BCD Code ✅ Decimal to BCD Conversion ✅ BCD to Decimal Conversion ✅ Excess-3 Code ✅ Decimal to Excess-3 Conversion ✅ Excess-3 to Decimal Conversion ✅ Gray Code ✅ Binary to Gray Code Conversion ✅ Gray Code to Binary Conversion ✅ Difference between BCD, Excess-3 and Gray Code ✅ Common mistakes in code conversions ✅ Solved practice examples ✅ Practice questions for students This lecture is useful for B.Tech, BCA, MCA, Diploma, and Computer Science students who are studying Digital Electronics, Digital Logic Design, Computer Organization, or Computer Architecture.
