The word "demodulated" is spelled with six syllables: /diːˈmɒdjuːleɪtɪd/. The "de-" prefix denotes removal, while "modulated" refers to a signal that has been altered for transmission. The word is commonly used in technical fields such as telecommunications and signal processing, where it describes the process of reversing modulation to retrieve the original signal. Understanding the phonetic transcription can aid in proper pronunciation and comprehension of this specialized term.
Demodulation is a signal processing technique that deals with the extraction of an information-bearing signal from its carrier wave, which is known as modulation. The term "demodulated" refers to the act of demodulating a signal.
Demodulation is crucial in communication systems as it allows the recovery of the original transmitted signal, which might have been modulated to enhance its transmission over a particular medium. It involves reversing the modulation process by extracting the original message signal from the carrier wave, thus retrieving the intended information.
The demodulated signal is the resultant output after the demodulation process has been applied to the modulated carrier wave. The demodulated signal precisely represents the original information that was encoded onto the carrier wave during the modulation stage. It should exhibit minimal distortion and retain the essential features of the original signal, such as amplitude, frequency, and phase.
Various demodulation techniques are employed depending on the modulation scheme employed in the communication system. Commonly used techniques include envelope detection, coherent demodulation, frequency demodulation, phase demodulation, and synchronous demodulation, among others.
In conclusion, "demodulated" pertains to the result of applying demodulation techniques to a modulated carrier wave, enabling the extraction of the original information-bearing signal. It is an essential process in communication systems, allowing the retrieval of the encoded message for further processing and decoding.
The word "demodulated" is derived from the combination of two words: "demo" and "modulated".
The word "demo" comes from the Latin word "dēmōnstrāre", which means "to demonstrate" or "to show". Over time, it was shortened to "demo" and began to be used as a prefix to indicate something that is representative or illustrating.
The word "modulated" comes from the Latin word "modulāre", which means "to measure" or "to regulate". In the context of communication or signals, modulation refers to the process of varying or adjusting the properties of a signal (such as amplitude, frequency, or phase) to carry information.
