Converting analog signals back into digital signals. A modem is a MOdulator/DEModulator.
The removal of intelligence from a transmission medium. The recovery, from a modulated carrier, of a signal having substantially the same characteristics as the original modulating signal.
The opposite of modulation in which baseband signal (information) is taken out from a modulated carrier. Contrast with modulation.
The process of reconstruction the original signal from a modulated one.
In telecommunications, the process of receiving and transforming an analog signal into its digital equivalent so that a computer can use the information.
The extraction of the modulation or information from a radio-frequency current
The process of retrieving information (data) from a modulated carrier signal. Reverse of modulation. DES: (Data Encryption Standard) A scheme approved by the National Bureau of Standards that encrypts data for security purposes. DES is the data- communications encryption standard specified by Federal Information Processing Systems.
The process of recovering information from a previously modulated carrier frequency. A modulated carrier is a wave, like sound, that has been modified in such a way that variations in such features as amplitude (wave height) and frequency (timing) represent meaningful information. In computer communications, demodulation is the means by which a modem converts data transmitted in audio form over a telephone line to the digital form that is needed by a computer, with as little distortion as possible.
The process of retrieving an original signal from a modulated carrier wave. This technique is used in modems to make communication signals compatible with computer signals. Compare with: modulation.
The act or process by which an output wave or signal is obtained from a carrier wave or signal, where the recovered wave or signal has the characteristics of the original modulating wave or signal. The reverse process of Modulation.
Converting signals from a wave form [analog] to pulse form [digital]. Contrast with modulation.
The process of restoring a signal to its original form at the receiving end of a transmission system.
Conversion of a signal from either digital or analog to its original form. Antonym: modulation.
The process of recovering the audio from the RF signal in a receiver.
Conversion of analog carrier signal to digital information.
Process of retrieving digital data from a modulated carrier wave.
The process of sensing variations in a radio frequency carrier and reconstructing the original modulating audio signal from them.
the process ofrecovery of a modulating signal from a modulated carrier
(electronics) the reception of a signal by extracting it from the carrier wave
The process of separating a modulated signal from its carrier signal and converting it back to its original state.
The process of recovering data from a radio and/or audio signal. Also see modulation.
The process of recovering, at the receiver, an original transmitted signal that has been modulated.
The process of recovering intelligence from a signal, some parameter of which was modified to carry the intelligence (see modulation).
Recovery of the original information (speech or data) that was modulated onto a radio frequency signal (also “detection”).
A step in the process by which an RF (radio frequency) carrier signal from the transmitter is changed to an audio signal.
To extract information from a modulated carrier wave.
Removal of the chop signal by the transputers. At this time, the raw data can not be accessed, only the demodulated data are stored.
Technique for retrieving information from a modulated signal. Demonstrated by the eponymous modem (modulator/demodulator).
The process of converting an analog telecommunications signal into a digital computer signal
Process for retrieving an information signal that has been modulated onto a carrier.
Process of returning a modulated signal to its original form. Modems perform demodulation by taking an analog signal and returning it to its original (digital) form.
This is the process of converting analog information (like over phone lines) into digital information (like in a computer). See "Modem" for more.
A signal-rectifying system that derives the modulating-signal component from the modulated carrier.
Process of retrieving an original signal from a carrier signal or wave.
The process of extracting the original signal from a modulated carrier.
The process of retrieving intelligence (data) from a modulated carrier wave. The reverse of "modulation. "
The process of extracting transmitted information from a carrier signal.
The process of retrieving digital (computer) data from a modulated analog (telephone) signal.
the process of retrieving data from a modulated signal. (See modulation, modem.)
Demodulation is the act of removing the modulation from an analog signal. Demodulating is necessary because the receiver system receives a modulated signal with specific characteristics and it needs to turn it to base-band.
