Wat is een modulator-demodulator (modem)? Wat je erover moet weten
Een modulator-demodulator, beter bekend als een modem, is een essentieel apparaat dat je verbinding met het internet mogelijk maakt. Een modem fungeert als een converter tussen digitale signalen die je computer begrijpt en analoge signalen die via je telefoonlijn of kabel worden verzonden.
Basics of Modulation and Demodulation - Microwaves & RF
Part 2 will also review the types of hardware needed for each type of modulation/demodulation format, and which modulator/demodulator performance parameters are most critical to achieving good communications-systems performance with high spectral efficiency.
What is Modulation? - GeeksforGeeks
A demodulator will convert the carrier variation of amplitude, frequency, or phase back to the message signal. There are three different types of demodulators for converting the AM (amplitude modulation), FM (frequency modulation), and PM (phase modulation) modulation schemes.
Modem vs. Router: Here's the Difference (And Why It Matters) - How-To Geek
Historically, the term "modem" is shorthand for modulator-demodulator. Modems were used to modulate the signals on telephone lines so that digital information could be encoded and transmitted over them and then demodulated---and decoded---on the other end.
What is a Modem (Modulator/Demodulator)? - Computer Hope
Short for modulator/demodulator, a modem is a hardware device that allows a computer to send and receive information over telephone lines. When sending a signal, the device converts ("modulates") digital data to an analog audio signal and transmits it over a telephone line.

What is Modulation and Demodulation? - Definition, Types, Differences ...
A demodulator is an electronic circuit that is mainly used to recover the information content from the modulated carrier wave. There are different types of modulation, and so are demodulators. The output signal via a demodulator may describe the sound, images, or binary data.
Modulator vs Demodulator-Difference between modulator,demodulator
Modulator converts input information bits into complex waveform. The parameters of output waveform is changed as per modulating input signal based on modulation type. Typical analog modulators include AM, FM and PM while digital modulators include ASK, FSK, PSK, 16QAM, 64QAM and 256QAM.
Demodulation - Definition, Techniques, Challenges and Applications
A demodulator will convert the carrier variation of amplitude, frequency, or phase back to the message signal. There are three different types of demodulators for converting the AM (amplitude modulation), FM (frequency modulation), and PM (phase modulation) modulation schemes.
Radio technology - Modulation, Demodulation, Signals | Britannica
Radio technology - Modulation, Demodulation, Signals: A carrier wave is a radio-frequency wave that carries information. The information is attached to the carrier wave by means of a modulation process that involves the variation of one of the carrier-frequency characteristics, such as its amplitude, its frequency, or its duration.
Modem - Wikipedia
A modulator-demodulator, commonly referred to as a modem, is a computer hardware device that converts data from a digital format into a format suitable for an analog transmission medium such as telephone or radio.
Modulation and Demodulation - MIT
This process of shifting the frequency spectrum of a signal is called modulation. As an example human voice spans a 4 kHz range or bandwidth, and is centered at 0 kHz.
6 - Channels, modulation, and demodulation - Cambridge University Press ...
Demodulation (channel decoding) is the corresponding process at the receiver of converting the received waveform into a (perhaps noisy) replica of the input bit sequence.

What You Need to Know About Modulators | DigiKey
Demodulators, on the other hand, take the modulated signal and output the information signal and the carrier signal. The carrier signal does not get further used. In a system, the modulator is placed before the transmitter while the demodulator comes after the receiver.
Modulation - Wikipedia
A modulator is a device or circuit that performs modulation. A demodulator (sometimes detector) is a circuit that performs demodulation, the inverse of modulation. A modem (from mod ulator– dem odulator), used in bidirectional communication, can perform both operations.
Channels, modulation, and demodulation - MIT OpenCourseWare
A major objective in designing the modulator and demodulator is to maximize the rate at which bits enter the encoder, subject to the need to retrieve the original bit stream with a suitably small error rate. Usually this must be done subject to constraints on the transmitted power and bandwidth.
Demodulation - Wikipedia
For example, in a modem, which is a contraction of the terms modulator/demodulator, a demodulator is used to extract a serial digital data stream from a carrier signal which is used to carry it through a telephone line, coaxial cable, or optical fiber.
Difference Between Modulation and Demodulation - GeeksforGeeks
The difference between modulation and demodulation is that modulation is connected at the transmission end while demodulation is connected at the receiver’s end. The transmission of frequency in modulation goes low to high while the transmission of frequency in demodulation goes high to low.
Modulator | Analog Devices
A modulator is an electronic circuit that superimposes a low-frequency (information) signal onto a high-frequency (carrier) signal for the purpose of wireless transmission.
