What is the primary purpose of a demultiplexer?

• A. A device to amplify signals
• B. A device used to convert digital signals to analog
• C. A device to separate two or more signals
• D. A device to combine multiple input signals into one output

Answer: (C)

The primary purpose of a demultiplexer is to separate multiple input signals into distinct output signals. This device takes a single input line and channels it to one of several output lines based on the value of selection signals. Essentially, a demultiplexer can be thought of as a switch that directs the input data to the appropriate output channel without any modification to the signal itself. In practical applications, demultiplexers are commonly used in digital circuits to route data from a single source to different destinations, enabling efficient data management in communication systems or digital signal processing. This functionality is essential in systems that require the distribution of information, allowing for precise control over data flow.
