Modem - Wikipedia
A modulator-demodulator or 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.
Difference between Modulation and Demodulation - Online Tutorials Library
The electronic circuit that is required to perform modulation is called modulator. The electronic circuit required to done demodulation is called demodulator or sometimes, detector. Process: In modulation, the message signal is added on a carrier wave for transmission. In demodulation, the message is separated from the carrier signal ...
FM modulator and demodulator design | TU Delft Repositories
The subsystems discussed in this report are the modulator and demodulator. The modulator, on the transmitter side, varies the carrier wave frequency, based on the input audio signal. The demodulator, on the receiver side, can detect these variations and retrieve the audio signal.
MC1496, MC1496B Balanced Modulators/ Demodulators - onsemi
Balanced Modulators/ Demodulators. These devices were designed for use where the output voltage is a product of an input voltage (signal) and a switching function (carrier). Typical applications include suppressed carrier and amplitude modulation, synchronous detection, FM detection, phase detection, and chopper applications.
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.

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.
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.
Modulators: Introduction & Measurement Schemes - Mini-Circuits Blog
In a demodulator (Figure 2b), the carrier is recovered from the incoming modulated signal and fed to 90° hybrid and modulated signal to the 0° hybrids. The I and Q ports contain the down converted intermediate-frequency (IF) signal.
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.
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.

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 modulator–demodulator), used in bidirectional communication, can perform both operations.
Demodulation - Wikipedia
Demodulation is extracting the original information-bearing signal from a carrier wave. A demodulator is an electronic circuit (or computer program in a software-defined radio) that is used to recover the information content from the modulated carrier wave. [1] There are many types of modulation so there are many types of demodulators.
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.
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.
