Which component is commonly used to implement a demultiplexer?

• A. Transistor
• B. Transformer
• C. Microcontroller
• D. Logic gates

Answer: (D)

A demultiplexer, often referred to as a demux, is a device that takes a single input signal and routes it to one of many output lines. The implementation of a demultiplexer relies on the principles of digital logic, making logic gates the essential components used in its construction. Logic gates such as AND, OR, and NOT gates can be arranged in various configurations to perform the necessary operations of selecting one output line based on the binary value of the control inputs. Each combination of control inputs activates a specific output, effectively directing the input signal to the intended pathway. While transistors are foundational elements in many electronic devices, and they can be used in the logic gate implementations, they do not directly serve the role of a demultiplexer themselves; rather, they are the building blocks of logic gates. Transformers, on the other hand, are primarily used in analog signal processing and power applications, not typically in digital logic circuits. Microcontrollers, though versatile, include integrated logic and control capabilities that could implement demux functions, but they are not solely dedicated components for this purpose. The correct choice emphasizes the fundamental role that logic gates play in digital communication and signal processing circuits, specifically in facilitating the selective routing functionality of a demultiplexer
