The process of re-creating the original modulating signal from the RF carrier is known as what?

The correct process of re-creating the original modulating signal from the RF carrier is referred to as demodulation. In communication systems, modulation is the technique used to encode information onto a carrier wave for transmission purposes. Once the modulated signal reaches its destination, demodulation is essential to extract the original message from the modulated carrier. This ensures that the information can be understood or further processed after its transmission.

Demodulation involves various methods, such as envelope detection, synchronous detection, or phase-locked loops, depending on the modulation scheme used (like AM or FM). Essentially, it reverses the modulation process, allowing the receiver to retrieve the intended signal accurately.

Understanding this process is crucial in fields like telecommunications, radio broadcasting, and data communication, where accurate retrieval of transmitted information from a carrier is necessary for effective communication.
