Form factor of any periodic wave is [RMS CURRENT]/[AVERAGE CURRENT].
For sinusoidal wave
RMS current=I/sqrt(2);
AVERAGE current=2I/pi;
Therefore,
Form factor=[I/sqrt(2)]/[2I/pi]
=pi/{2*sqrt(2)}
=1.11
A sine wave has no harmonics. It only has a fundamental, so the value of the 2nd, 3rd, and 12th harmonics of a sine wave is zero.
It is a sine wave form coupled with either a DC component or other sine waves or both.The official definition of the word waveform is "a curve showing the shape of a wave at a given time."
cos wave
It's called a sine wave because the waveform can be reproduced as a graph of the sine or cosine functions sin(x) or cos (x).

Form factor is (RMS value)/(average absolute value) For sine wave form factor = (1/sqrt(2))/(2/pi) = about 1.11
form factor tell about the purity of sine wave
i dont know,,,give me ans
due to the form factor .as the form factor of sine wave is 1.1 so, we use its multiples .
A sine wave has no harmonics. It only has a fundamental, so the value of the 2nd, 3rd, and 12th harmonics of a sine wave is zero.
It is more reasonable to use square wave rather than sine wave signal to determine slew rate. Both signal sources serve as a functional generator with the sine wave providing high purity waves.Ê
A wave front has a form that is a surface of a sphere.
None - except that we have a grasp of the mathematical properties of sine waves. Sine waves seldom occur in nature ... but they often come close enough to be approximated by a sine wave.
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 saw tooth wave form superimposed over a square wave form is TPZi wave form. Most of the Inverters use this technology instead of pure sine wave form of out put.
By shifting the sine wave by 45 degrees.
A sine wave is the graph of y = sin(x). It demonstrates to cyclic nature of the sine function.
