demodulating
[หdiหmoสหdสuหleษชtษชล ]
Definition
signal processing
Demodulating refers to the process of extracting the original information-bearing signal from a modulated carrier wave. This process is essential in telecommunications where data must be transmitted over various mediums and demodulated for the end user. Different demodulation techniques exist based on the modulation type used such as amplitude, frequency, or phase modulation.
Synonyms
Examples of usage
- The radio receiver is tasked with demodulating the incoming signal.
- In satellite communications, demodulating the signal is crucial for data transmission.
- Engineers must choose the appropriate method for demodulating signals.
- The device is highly efficient at demodulating complex waveforms.

Origin of 'demodulating'
The term 'demodulate' is derived from the prefix 'de-', implying removal or reversal, combined with the term 'modulate', which comes from the Latin 'modulatus', meaning 'measured' or 'regulated'. In telecommunications, modulation involves varying one or more properties of a carrier signal in relation to a message signal, while demodulation is the reverse process, intended to retrieve the original message. The concept gained prominence with the advent of radio technology in the early 20th century, as engineers and researchers sought ways to improve the clarity and efficiency of communication systems. Demodulation techniques have evolved significantly, with advances in digital signal processing leading to more sophisticated methods of extracting information from modulated signals.
