J. (2013). How does noise affect amplitude and latency measurement of event-related potentials (ERPs)? A methodological critique and simulation study. Psychophysiology 50, 174-186. doi: 10.1111/psyp.12001Clayson, P.E., Baldwin, S.A., Larson, M.J., 2013. How does noise affect amplitude...
A wave is a disturbance of a physical quantity traveling in space. The simplest form of a wave is a sine wave propagating along one dimension x in a time t, characterized by A(x,t)=A0sin(kx−ωt), where A can stand for displacement (wave on a string or on water), ...
How does light act as a wave? How does it act as a ray?Wave-Particle DualityLight sometimes acts as a wave and sometimes also acts as a particle or ray. The phenomenon of having these two characteristics is called the wave-particle duality of light. In the Answer and Explanation section,...
You know how a sine wave looks, and if you have the amplitude and period it's easy enough to rough in. For the one curve with a phase offset I might find the first zero crossing to fix the shift. After that it's handled the same way -- mark off periods from the zero crossin...
There is also the amplitude of the sound wave, the magnitude of the fluctuation of a wave from equilibrium. The amplitude determines the loudness of the sound. So if you pluck a guitar string harder, it will displace more air and create a louder sound—even more with the help of an ampl...

and a further group of eight was tested at 86 dB SPL.Interestingly, the results demonstrated that the average amplitude level of the music playback did not affect the noise detection results. At each test level, the ability of listeners to detect the noise distortion depended on the relative ...
It takes far less effort to influence where dust settles or to shatter a glass than it takes to lift objects from the ground. Ordinary sound waves are limited by their linear nature. Increasing the amplitude of the wave causes the sound to be louder, but it doesn't affect the shape of ...
You should have an idea of the smallest change in a signal that you want to see. Systems with the highest dynamic range provide the best possible vertical axis measuring resolution. But you also have to consider the time axis, because if changes in amplitude fall between samples, they cannot...
This creates a stream of pulses at the carrier frequency. Within each period of the carrier, the duty ratio of the PWM pulse is proportional to the amplitude of the audio signal. In the example of Figure 7, the audio input and triangular wave are both centered around 0 V, so that for...
