A sinewave could only have a single frequency if it was on forever.Mac said:The simple answer is that in popular usage a sine wave is only a single
frequency.
But in the real world there is always noise riding on that sine wave, and
possibly other sine waves of smaller amplitude. So if you look at your
sine wave on a spectrum analyzer, you will find that the peak is not a
spike, such as you would see in a purely mathematical Fourier transform,
but is spread out over some frequency range.
You would also see that there are harmonics present. That is to say, there
are components at 2x, or 3x or some higher integer multiple of the
fundamental sine wave frequency.
What made you think to ask this question here instead of, say,
sci.electronics.basic?

The switching envelope will otherwise interact with the sinewave itself.
Which is what windowing is all about.

People here seem to be forgetting it's a *pure* sine wave that
constitutes a single frequency. Any form of ' irregular sine wave'
will contain components of other frequencies and they may not be
apparent from visual examination of the wave on an oscilloscope. Their
presence undeniable, nevertheless.

Digital communication engineers prefer viewing Sine waves and all
periodic functions in the frequency domain , which actually implies
analyzing their Fourier transforms. Accordingly you can view a Sine
wave as the sum of an infinite number of sinusoids having frequency
components which are integral multiples of the fundamental frequency.
ha ha You answer to the Op that that he needs to check up Simple"theJackal"
** Huh ??
Better lay off them hallucinogenics - mate.

ha ha You answer to the Op that that he needs to check up Simple
Harmonic motion to understand a Sine wave and now this . oh help my
soul!
You need basic education man ... The "average" engineer knows what
Monsier Joseph Fourier discovered more then 200 years ago
Sine (w*t) = a + (sum of ( bn* Cos n *w* t + phi (n)) The addition
is carried over for n that varies from 1 to infinity.

** You are a schizo, fucking IDIOT - Piss Off .!!!!!!!!!!!!
** Absoulute rubbish.
A pure sine wave is a SINGLE frequency.

Keep panting in your bottomless pit wannabe engineer.Must be one of them wannabe terrorist imbeciles.
