Why can a wave be expressed with a sine function?

The equation is A × sign(sinωt), where the sign function is self-explanatory*. There's nothing 'sine-like' about the wave, but we still see sin. This is useful because the sine function will alternate between …

0. I think the question is not particularly MCU/board specified but I will be trying it on STM32F4-DISC board. I was thinking of how to output a nice sinewave from a normal GPIO output pin, but I was not able to find a proper methodology. I am asking for a method of thinking, a guide rather than the complete solution.

Why is sine wave preferred over other waveforms?

Sinusoidal functions are 'eigenfunctions' of linear systems. This means that if the input is sin(t) the output is of the form A ⋅ sin(t + ϕ) The function family stays the same and is only scaled in amplitude and shifted in time. This gives us a good idea what happens to the signal if it propagates through the system.

waveform

It draws current in spikes at the tips of the waves. Since the impedance of the power line isn't zero, this non-sinusoidal current draw causes some non-sinusoidal voltage. Since non-sinusoidal voltage is undesirable, there are regulations about how much the current draw is allowed to vary from sinusoidal for high power loads.

Sinusoidal

Sinusoidal. The term sinusoidal is used to describe a curve, referred to as a sine wave or a sinusoid, that exhibits smooth, periodic oscillation. Sinusoids occur often in math, physics, engineering, signal processing …

Example 1.2.1. The figure below is a graph of the simple harmonic motion of a particle of string through which an harmonic transverse wave is passing (the displacement is parallel to the y-axis, and the motion is along the x-axis). The position (x-value) of the oscillating particle is 5m, as indicated on the graph.

A sound wave is a longitudinal wave, but a sinusoid is a transverse wave so the sinusoidal representation of a sound wave can create confusion. In the transverse representation, you can think of the horizontal axis as the ...

Sinusoidal Waveforms or Sine Wave in an AC Circuit

Therefore a sinusoidal waveform has a positive peak at 90 o and a negative peak at 270 o. Positions B, D, F and H generate a value of EMF corresponding to the formula: e = Vmax.sinθ. Then the waveform shape produced by our simple single loop generator is commonly referred to as a Sine Wave as it is said to be

Wavelength Calculator λ = v/f

Waves are signals that travel through air, water, light, and even wire as in the case of an electrical AC current. Wavelength is the distance between 2 identical points on a sinusoidal wave. If you know …

Teacher Support [BL] For sound, a higher frequency corresponds to a higher pitch while a lower frequency corresponds to a lower pitch. Amplitude corresponds to the loudness of the sound. [BL] [OL] Since sound at all frequencies has the same speed in air, a change in frequency means a change in wavelength. [Figure Support] The same speaker is …

Normalize a sinusoidal wave to a fixed voltage [closed]

There are a couple of ways to do this too:-. Amplify the signal until it is limited or use a comparator to produce a square wave output, then remove the harmonics with a low pass filter so it becomes (almost) a pure sine wave again. Feed the signal into a Phase Locked Loop which controls the frequency of an oscillator.

LTSpice: how to setup sinusoidal or exponential voltage …

DC Offset adds a DC level to your sine wave signal e.g. 1V DC Offset means your sine wave will "oscillate" around 1V rather than 0V. Frequency is the number of cycles the sine wave will complete in a second. Tdelay adds delay before starting the source. I would say you experiment with these values and you will learn alot more.

The RMS velocity of the wave form is given as. Vrms = 0.707 x max amplitude or peak value. = 0.0707 x 150 = 106.05 volts. The angle of a sine wave is a function of its frequency, as we know the sine wave's angular velocity, so we can find out the frequency of the waveform. By using the relation between ω and f.

Using sinusoids to represent sound waves

In general, anything of the form. f(x, t) = w(ωt − kx), f ( x, t) = w ( ω t − k x), where w w is any function, describes a traveling wave. Sinusoids turn up very often because the …

Sinusoidal waves don't have harmonics because it's exactly sine waves which combined can construct other waveforms. The fundamental wave is a sine, so …

Why are AC quantities represented by sine waves always?

Firstly, a cosinusoid is just a sine wave which has been shifted by a phase of $pi / 2$. So the two are equivalent ways of describing a wave. One can describe a wave as a triangular wave, or a square wave or any other wave form. In fact, square waves are used as the input to all sorts of logical circuits and digital electronics.

16.2 Mathematics of Waves

Finding the Characteristics of a Sinusoidal Wave. To find the amplitude, wavelength, period, and frequency of a sinusoidal wave, write down the wave function in the form y (x, t) = A sin (k x − ω t + ϕ). y (x, t) = A sin (k x − ω t + ϕ). The amplitude can be read straight from the equation and is equal to A.

Why 'sine' wave of alternating current?

Also at each stage of transformation the waveform would slowly approach a perfect sine wave due to the filtering nature of these losses. So one just sticks to the sine wave as generated by your rotating machine. @TheDude the graph in the third section is wrong, since the current will be zero. (The capacitor blocks the DC produced by the diode.)
