A periodic wave done using a rope is for example a sine wave.
It is the form of Simple Harmonic Motion, and traces the equation y = sin(x) where y=1 and -1 are the peaks.
A sine wave oscillates.
By shifting the sine wave by 45 degrees.
sine wave. It is a smooth, repetitive oscillation that is easy to represent graphically as a simple curve. Sine waves have a clear pattern that is easy to predict and visualize.
Fourier analysis shows that the saw wave is constructed through manipulation of a sine wave, I can't remember the maths behind it but it's definitely a sine wave.
Sine wave
The type of wave made up of a sine wave plus all of its odd harmonics is called a square wave. It is commonly used in music synthesis and signal processing.
The Fourier transform of a sine wave is a pair of delta functions located at the positive and negative frequencies of the sine wave.
Do you mean "How do sine waves generate ?" Or perhaps you mean "How are sine waves generated?" Or something else, perhaps? No one can answer a question that is incomprehensible.
A sine wave is the graph of y = sin(x). It demonstrates to cyclic nature of the sine function.
The voice is not a sine wave.
a phase shifted sine wave of a different amplitude.
Sine wave is considered as the AC signal because it starts at 0 amplitude and it captures the alternating nature of the signal. Cosine wave is just a phase shift of the sine wave and represents the same signal. So, either sine or cosine wave can be used to represent AC signals. However, sine wave is more conventionally used.
