DEMODULATOR Meaning and
Definition
-
A demodulator is an electronic device or circuit utilized to recover the original information from a modulated carrier signal. It is an integral component in communication systems that employ modulation techniques, such as amplitude modulation (AM), frequency modulation (FM), or phase modulation (PM), to transmit signals over a medium.
The demodulator effectively performs the opposite function of a modulator, which converts the information signal into a modulated carrier signal suitable for transmission. It acts as a detector, extracting the modulating signal, also known as the baseband signal, from the carrier signal.
The demodulator receives the modulated signal as input and isolates the desired information signal while discarding the carrier signal and any unwanted noise or interference that may be present. This information signal can be audio, video, data, or any other form of transmitted information.
Demodulators are widely employed in various applications, including radio and television broadcasting, satellite communications, wireless communication systems, and digital communications. They may be implemented as standalone devices or integrated into other equipment such as receivers, transceivers, televisions, or audio systems.
Different types of demodulators exist to cater to different modulation schemes, such as envelope detection demodulators for AM, frequency discriminator or phase-locked loop (PLL) demodulators for FM, and coherent demodulators for PM. Overall, demodulators play a critical role in the successful reception and decoding of transmitted information in communication systems.

Etymology of DEMODULATOR
The word "demodulator" originated from combining the prefix "de-" (meaning "reverse" or "undo") with the noun "modulator".
The term "modulator" comes from the Latin word "modulatus", which means "measured", derived from the verb "modulare" meaning "to regulate" or "to measure".
When the "de-" prefix is added to "modulator", it creates "demodulator", which essentially conveys the concept of "undoing" or "reversing" the modulation process. In the context of electronics or telecommunications, a demodulator is a device or component that extracts the original information signal from a modulated carrier wave.
