Modulation is the process of converting data into radio waves by adding information to an electronic or optical carrier signal. A carrier signal is one with a steady waveform (a constant amplitude and frequency)
QAM is used to achieve greaterspectrum efficiency. This is accomplished by utilizing both the amplitude and phase components to modulate, or alter, the waveform. In this scenario, the QAM waveform consists of two signals, also known ascarrierwaves. One signal is called theI signal, and the ot...
This amplitude is currently used as a target value in the design of future CMB experiments with the ultimate goal of measuring it at more than five standard deviations. Here we evaluate how stable are the predictions of the Starobinski model on $r$ considering the experimental uncertainties on ...

In 1969, Italian physicist Gabriele Veneziano wrote down a formula describing the scattering of four strings, the now-famous Veneziano amplitude. Veneziano was trying to describe the physics of particles like the proton and neutron, not strings. In the following years, physicists around the world ...
other faster generating stronger and stronger gravitational waves. As result, they lose energy and are drawn together even more rapidly increasing the frequency and amplitude of the gravitational waves they create until they are within the range frequencies of LIGO and other interferometers can "hear....
If questioning interpretation of experimental evidence is crackpot then you would have to add Galileo and Einstein to your collection. I can accept the existence of waves and all the experimental evidence for them, but in every graphical representation of those waves amplitude is shown as well as...

When two waves meet each other and both peaks of a frequency coincide with each other, the resulting amplitude for that frequency can be at most twice as loud. The same can happen with the troughs of a wave. When a peak and a trough (the high point and low point of a wave) meet,...
A wave (whether it's a sound wave, ocean wave, radio wave, or any other kind of wave) can be described by its amplitude (height or power) and frequency (how close together each wave peak is from the next). In doing so, a sine curve of a particular height and frequency is generate...
