Code Converts and Multiplexers Questions and Answers

Take Exam

Code Converters and Multiplexers are crucial topics in Digital Electronics aptitude questions and answers for exams like GATE, ISRO, DRDO, and BARC. These devices form the backbone of digital systems, helping in signal conversion and data routing. A code converter transforms one type of binary code to another, such as BCD to Gray or binary to excess-3. A multiplexer, on the other hand, selects one of many input signals and forwards it to a single output line. Understanding these concepts strengthens logical and numerical reasoning, especially for electronics and communication aspirants. Explore detailed aptitude questions with solutions PDF and explanations to boost your preparation and master problem-solving in digital circuits effectively.
