Do you mean "How do sine waves generate <something you think they generate>?" Or perhaps you mean "How are sine waves generated?" Or something else, perhaps? No one can answer a question that is incomprehensible.
The Fourier transform of a sine wave is a pair of delta functions located at the positive and negative frequencies of the sine wave.
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.
A sine wave oscillates.
The wavelength and frequency of a sine wave are inversely related. This means that as the wavelength increases, the frequency decreases, and vice versa. The product of the wavelength and frequency of a sine wave is always equal to the speed of the wave.
To find the equation of a sine wave, you need to know the amplitude, period, and phase shift of the wave. The general form of a sine wave equation is y Asin(B(x - C)), where A is the amplitude, B is the frequency (related to the period), and C is the phase shift. By identifying these values from the given information or graph, you can write the equation of the sine wave.
By shifting the sine wave by 45 degrees.
it is DC powered, but can generate sawtooth or triangular wave AC if wired up properly. it cannot generate sine wave AC, although with an opamp wave shaping circuit the triangular AC waveform can be reshaped to a rough approximation of a sine wave.
Generating Sine and Cosine Signals (Use updated lab)
A=2; t = 0:0.0005:1; x=A*sawtooth(2*pi*5*t,0.25); %5 Hertz wave with duty cycle 25% plot(t,x); grid axis([0 1 -3 3]); The above code can generate sine wave using Matlab.
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.
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.
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).
