What is modulation? - Definition from WhatIs.com

Modulation is the addition of information to an electronic or optical carrier signal. A carrier signal is one with a steady waveform -- constant height (amplitude) and frequency. Information can be added to the carrier by varying its amplitude , frequency , phase , polarization (for optical signals), and even quantum-level phenomena like spin .

This approach is called angle modulation, and includes frequency modulation (FM) and phase modulation (PM). The amplitude of the carrier is maintained constant. The major advantage of this approach is that it allows the trade-off ...

3.7 Quadrature Amplitude Modulation (QAM) QAM is a bandwidth efficient signaling scheme that, unlike CPM, does not possess a constant envelope property. 6 Unlike CPM waveforms, QAM needs to operate in the linear region of a power amplifier to avoid any signal compression and hence degradation. For this reason, among others, when choosing QAM as a signaling scheme, the waveform designer is ...

Modulation - Music Theory Academy

Modulation describes the process where a piece of music changes from one key to another key.. When you start writing a piece of music one of the first things you do is choose a key to compose in. This choice of key determines the scale you use, how many sharps and flats there are and what chords you can use. This key is sometimes called the “home key”.

we can see that this sinusoid has 3 parameters that can be altered, to affect the shape of the graph. The first term, A, is called the magnitude, or amplitude of the sinusoid. The next term, is known as the frequency, and the last term, is known as the phase angle. All 3 parameters can be altered to transmit data. The sinusoidal signal that is used in the modulation is known as the carrier ...

Modulation (music) - Wikipedia

In music, modulation is the change from one tonality (tonic, or tonal center) to another.This may or may not be accompanied by a change in key signature.Modulations articulate or create the structure or form of many pieces, as well as add interest. Treatment of a chord as the tonic for less than a phrase is considered tonicization.. Modulation is the essential part of the art.

Amplitude Modulation | Academo.org - Free, interactive ...

The \( y_2\) waveform is acting as a modulator and creates an amplitude envelope. This means its magnitude is determining the magnitude of \( y_{1\times2} \). When the value of \( A_2 \) is zero, the modulator has a constant value of 1, and the line \( y_{1\times2} \) is exactly equal to \( y_1 \) meaning you will not hear any variation in loudness. If you increase \( f_2 \) higher and higher ...
