A: Since it can be considered a full circle then then there will be 4 quadrant for 360 degrees
cos wave
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'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).
The fourier series of a sine wave is 100% fundamental, 0% any harmonics.
Since a sine wave is described by the trigonometric sin(x) function, which is symmetrical, the sine wave is also symmetrical, unless there is a DC bias, in which case it is not. (It depends on your definition of symmetry)
if a signal is not a pure sine wave it must contain harmonics
By shifting the sine wave by 45 degrees.
how squre wave convert into sine wave incase of inverter
The Fourier transform of a sine wave is a pair of delta functions located at the positive and negative frequencies of the sine wave.
A sine wave is the graph of y = sin(x). It demonstrates to cyclic nature of the sine function.
Because the laws of basic AC circuit theory only apply to a true sine wave. Other waveforms, such as square or sawtooth, are imperfect recreations of a sine wave with many harmonic frequencies present.
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.
