Sine wave - Wikipedia
A sine wave, sinusoidal wave, or sinusoid (symbol: ∿) is a periodic wave whose waveform (shape) is the trigonometric sine function. In mechanics , as a linear motion over time, this is simple harmonic motion ; as rotation , it corresponds to uniform circular motion .
2.1.2 Properties of Sine Waves – Digital Sound & Music
A sine wave is a graph of a sine function . In the graph, the x-axis is the horizontal axis, and the y-axis is the vertical axis. A graph or phenomenon that takes the shape of a sine wave – oscillating up and down in a regular, continuous manner – is called a sinusoid.

Above is a representation of a sine wave, the simplest wave that may be created. It represents the displacement of a simple rotating vector (such as the second hand of a clock).
1.2: Sine Waves - Physics LibreTexts
A particularly simple kind of wave, the sine wave, is illustrated in Figure \(\PageIndex{2}\):. This has the mathematical form \[h(x)=h_{0} \sin (2 \pi x / \lambda)\label{1.1}\] where h is the displacement (which can be either longitudinal or transverse), h 0 is the maximum displacement, also called the amplitude of the wave, and λ is the ...
Acoustic Phonetics: Properties of sine waves - University of …
Three useful things to measure about a sine wave are: amplitude; wavelength; frequency . Amplitude (loudness) The amplitude of a wave is the size of the pressure difference it causes. Amplitude is usually measured in decibels (abbreviated dB). People will hear hear amplitude as loudness. Wavelength
Sine wave - Simple English Wikipedia, the free encyclopedia
A sine wave is a curve, a continuous function with this shape: This is a picture of a sine wave. All waves can be made by adding up sine waves. The sine wave has a pattern that repeats. The length of this repeating piece of the sine wave is called the wavelength.
Circles Sines and Signals - Sine Wave Properties - GitHub Pages
Sine waves are utterly fascinating. Their peculiar nature makes them particularly well suited to act as the “atomic” components of complex signals. I’d encourage you to play around with sinusoids and the trigonometric identities.
• A simple periodic wave has the shape of a sine wave (may be phase-shifted!) • Not many real-world sound waves are sine waves • But, as we will soon see, complex periodic waves can be described in terms of sine waves → We need to understand the properties of sine waves for doing acoustic analysis 25
Characteristics of Sinusoidal Signals (Sine Waves)
2020年5月3日 · A sine wave with an amplitude of 5 V, for example, has a maximum value of +5 V and a minimum value of –5 V. Frequency tells us how quickly the sinusoid completes full cycles. This important characteristic influences the maximum rate at which a sinusoidal signal can transmit information and determines how a sinusoidal signal will be affected ...
