demodulation
- noun
- /ˌdɛmədʒʊˈleɪʃən/
- Specialized
- The engineer explained the demodulation process, which retrieves the original audio from the radio wave.
Examples
-
And the demodulation of course involves multiplying by the carrier and doing appropriate low pass filtering to finally get the signal back.

The raw EMG is processed much like AM radio demodulation.

Note: most of our tapes are recorded in pre-detection mode, meaning that the analog data was written to the tapes before demodulation.

In the integrated design, the transport detects several stream errors, including a direct signal from the demodulation device, error indicators in the stream, continuity errors indicating missing packets, and table section errors.

Things like the IF of a receiver being directly recorded to high-speed tape (1-inch at 240 ips) for playback and demodulation later.

The second digital filter consists of an equalizer, which eliminates interference due to reflections in the transmission path, and a phase tracker, which corrects for residual phase noise in the demodulation process.

The process of demodulation is essential for understanding how radio signals transmit information.

In telecommunications, effective demodulation ensures that data is accurately extracted from modulated signals.

Morphology
demodulation = demodulate (transparent) = de + modulat + ion
This is a standard process noun formed from the verb 'demodulate' with '-ion'.
Etymology
Demodulation comes from the part de- meaning 'remove' and modulation from modulate meaning 'to change'. So demodulation is the act of removing the changes from a signal to get the original information, which is the same idea used in a modem.
