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
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
French: démodulation A process whereby a modulated signal is returned to its original form A demodulator is a component of a data set or modem which converts analogue data to digital data by receiving tones sent over a communication line (See modulation )
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
The process of extracting information from a modulated signal that arrives over a transmission line or telephone connection Demodulation usually occurs in a device called a modem Also see modulation and carrier
A device that recovers the original signal from a modulated carrier signal, such that the characteristics of the original are faithfully reproduced Implements the process of Demodulation
